Synthesis and characterization of brain penetrant prodrug of neuroprotective D-264: Potential therapeutic application in the treatment of Parkinson’s disease

Parkinson’s disease (PD) is one of the major debilitating neurodegenerative disorders affecting millions of people worldwide. Progressive loss of dopamine neurons resulting in development of motor dysfunction and other related non-motor symptoms is the hallmark of PD. Previously, we have reported on the neuroprotective property of a potent D3 preferring agonist D-264. In our goal to increase the bioavailability of D-264 in the brain, we have synthesized a modified cysteine based prodrug of D-264 and evaluated its potential in crossing the blood-brain barrier. Herein, we report the synthesis of a novel modified cysteine conjugated prodrug of potent neuroprotective D3 preferring agonist D-264 and systematic evaluation of the hydrolysis pattern of the prodrug to yield D-264 at different time intervals in rat plasma and brain homogenates using HPLC analysis. Furthermore, we have also performed in vivo experiments with the prodrug to evaluate its enhanced brain penetration ability.

Acute Respiratory Distress Syndrome: Bench-to-Bedside Approaches to Improve Drug Development

Despite 50 years of extensive research, no definite drug is currently available to treat acute respiratory distress syndrome (ARDS), and the supportive therapies remain the mainstay of treatment. To improve drug development for ARDS, researchers need to deeply analyze the ?omics? approaches, reevaluate the suitable therapeutic targets, resolve the problems of inadequate animal modeling, develop the strategies to reduce the heterogeneity, and reconsider new therapeutic and analytical approaches for better designs of clinical trials.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 19771-63-2, and how the biochemistry of the body works.category: thiazolidine

New insights into estrogenic regulation of O6-methylguanine DNA-methyltransferase (MGMT) in human breast cancer cells: Co-degradation of ER-alpha and MGMT proteins by fulvestrant or O6-benzylguanine indicates fresh avenues for therapy

Endocrine therapy using estrogen receptor-alpha (ER-alpha) antagonists for attenuating horm2one-driven cell proliferation is a major treatment modality for breast cancers. To exploit any DNA repair deficiencies associated with endocrine therapy, we investigated the functional and physical interactions of ER-alpha with O6-methylguanine DNA methyltransferase (MGMT), a unique DNA repair protein that confers tumor resistance to various anticancer alkylating agents. The ER-alpha -positive breast cancer cell lines (MCF-7, T47D) and ER- negative cell lines (MDAMB- 468, MDAMB-231), and established inhibitors of ER-alpha and MGMT, namely, ICI-182,780 (Faslodex) and O6-benzylguanine, respectively, were used to study MGMT-ER interactions. The MGMT gene promoter was found to harbor one full and two half estrogen-responsive elements (EREs) and two antioxidant-responsive elements (AREs). MGMT expression was upregulated by estrogen, downregulated by tamoxifen in Western blot and promoter-linked reporter assays. Similarly, both transient and stable transfections of Nrf-2 (nuclear factor-erythroid 2-related factor-2) increased the levels of MGMT protein and activity 3 to 4-fold reflecting novel regulatory nodes for this drugresistance determinant. Of the different ER-alpha antagonists tested, the pure anti-estrogen fulvestrant was most potent in inhibiting the MGMTactivity in a dose, time and ER-alpha dependent manner, similar to O6-benzylguanine. Interestingly, fulvestrant exposure led to a degradation of both ER-alpha and MGMT proteins and O6-benzylguanine also induced a specific loss of ER-alpha and MGMT proteins in MCF-7 and T47D breast cancer cells with similar kinetics. Immunoprecipitation revealed a specific association of ER-alpha and MGMT proteins in breast cancer cells. Furthermore, silencing of MGMT gene expression triggered a decrease in the levels of both MGMT and ER-alpha proteins. The involvement of proteasome in the drug-induced degradation of both proteins was also demonstrated. Fulvestrant enhanced the cytotoxicity of MGMT-targeted alkylating agents, namely, temozolomide and BCNU by 3 to 4-fold in ER-alpha positive cells, but not in ER-negative cells.We conclude that MGMTand ER-alpha proteins exist as a complex and are co-targeted for ubiquitin-conjugation and subsequent proteasomal degradation. The findings offer a clear rationale for combining alkylating agents with endocrine therapy.

Pharmacology and structural analysis of ligand binding to the orthosteric site of glutamate-like GluD2 receptors

The GluD2 receptor is a fundamental component of postsynaptic sites in Purkinje neurons, and is required for normal cerebellar function. GluD2 and the closely related GluD1 are classified as members of the ionotropic glutamate receptor (iGluR) superfamily on the basis of sequence similarity, but do not bind L-glutamate. The amino acid neurotransmitter D-Ser is a GluD2 receptor ligand, and endogenous D-Ser signaling through GluD2 has recently been shown to regulate endocytosis of a-amino- 3-hydroxy-5-methyl-4-isoxazolepropionic acid-type iGluRs during synaptic plasticity in the cerebellum, such as long-term depression. Here, we investigate the pharmacology of the orthosteric binding site in GluD2 by examining the activity of analogs of D-Ser and GluN1 glycine site competitive antagonists at GluD2 receptors containing the lurcher mutation (GluD2LC), which promotes spontaneous channel activation. We identify several compounds that modulate GluD2LC, including a halogenated alanine analog as well as the kynurenic acid analog 7-chloro- 4-oxo-1H-quinoline-2-carboxylic acid (7-chlorokynurenic acid; 7-CKA). By correlating thermodynamic and structural data for 7-CKA binding to the isolated GluD2 ligand binding domain (GluD2-LBD), we find that binding 7-CKA to GluD2-LBD differs from D-Ser by inducing an intermediate cleft closure of the clamshell-shaped LBD. The GluD2 ligands identified here can potentially serve as a starting point for development of GluD2- selective ligands useful as tools in studies of the signaling role of the GluD2 receptor in the brain.

Skeletal muscle atrogenes: From rodent models to human pathologies

Skeletal muscle atrophy is a common side effect of most human diseases. Muscle loss is not only detrimental for the quality of life but it also dramatically impairs physiological processes of the organism and decreases the efficiency of medical treatments. While hypothesized for years, the existence of an atrophying programme common to all pathologies is still incompletely solved despite the discovery of several actors and key regulators of muscle atrophy. More than a decade ago, the discovery of a set of genes, whose expression at the mRNA levels were similarly altered in different catabolic situations, opened the way of a new concept: the presence of atrogenes, i.e. atrophy-related genes. Importantly, the atrogenes are referred as such on the basis of their mRNA content in atrophying muscles, the regulation at the protein level being sometimes more complicate to elucidate. It should be noticed that the atrogenes are markers of atrophy and that their implication as active inducers of atrophy is still an open question for most of them. While the atrogene family has grown over the years, it has mostly been incremented based on data coming from rodent models. Whether the rodent atrogenes are valid for humans still remain to be established. An ?atrogene? was originally defined as a gene systematically up- or down-regulated in several catabolic situations. Even if recent works often restrict this notion to the up-regulation of a limited number of proteolytic enzymes, it is important to keep in mind the big picture view. In this review, we provide an update of the validated and potential rodent atrogenes and the metabolic pathways they belong, and based on recent work, their relevance in human physio-pathological situations. We also propose a more precise definition of the atrogenes that integrates rapid recovery when catabolic stimuli are stopped or replaced by anabolic ones.

In Vivo Selective Modulation of Tissue Glutathione in a Rat Mammary Carcinoma Model

Glutathione (GSH) is known to play a role in cellular sensitivity to some chemotherapeutic agents and to radiation. Depletion of cellular GSH has been demonstrated to result in enhanced toxicity of these drugs, and this approach is being explored in the clinic as a form of biochemical modulation, using the drug buthionine sulfoximine (BSO). The fact that some drug-resistant cell lines have increased glutathione levels, and that enhancing GSH concentrations in animal tissues protects against a variety of xenobiotic agents, suggest a different potential approach to improving anti-cancer therapy. We have examined the efficacy of the cysteine “pro-drug” L-2-oxothiazolidine-4-carboxylate (OTZ) at enhancing normal tissue versus tumor GSH. Animals were treated with OTZ or BSO, and the concentrations of GSH in normal tissues and tumor were measured. We found that the presence of the tumor itself decreased bone marrow GSH, but that OTZ significantly increased it in this setting. Interestingly, OTZ administration significantly depleted tumor GSH levels to the same level as did BSO. OTZ could offer a selective biochemical modulation of GSH.

The role of metabotropic glutamate receptors in addiction: Evidence from preclinical models

Addiction is a chronic disorder characterised by repeated bouts of drug taking, abstinence and relapse. The addicted state may be in part due to drug-induced neuroadaptations in the mesocorticolimbic and corticostriatal pathways. Recently focus has been on the role of aberrant glutamate transmission and its contribution to the hierarchical control over these systems. This review will expand our current knowledge of the most recent advances that have been made in preclinical animal models that provide evidence that implicate metabotropic glutamate receptors (mGluRs) in contributing to the neuroadaptations pertinent to addiction, as well as the role of Homer proteins in regulating these responses. The recent discovery of receptor mosaics will be discussed which add an additional dimension to the complexity of understanding the mechanism of glutamate mediated behaviours. Finally this review introduces a new area related to glutamatergic responses, namely microRNAs, that may become pivotal in directing our future understanding of how to best target intervention strategies to prevent addictive behaviours.

Pharmacological stimulation of nuclear factor (erythroidderived 2)-like 2 translation activates antioxidant responses

Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is the master regulator of the antioxidant response, and its function is tightly regulated at the transcriptional, translational, and posttranslational levels. It is well-known that Nrf2 is regulated at the protein level by proteasomal degradation via Kelch-like ECHassociated protein 1 (Keap1), but how Nrf2 is regulated at the translational level is less clear. Here, we show that pharmacological stimulation increases Nrf2 levels by overcoming basal translational repression. We developed a novel reporter assay that enabled identification of natural compounds that induce Nrf2 translation by a mechanism independent of Keap1-mediated degradation. Apigenin, resveratrol, and piceatannol all induced Nrf2 translation. More importantly, the pharmacologically induced Nrf2 overcomes Keap1 regulation, translocates to thenucleus, and activates the antioxidant response. We conclude that translational regulation controls physiological levels of Nrf2, and this can be modulated by apigenin, resveratrol, and piceatannol. Also, targeting this mechanism with novel compounds could provide new insights into prevention and treatment of multiple diseases in which oxidative stress plays a significant role.

Role of oxidative stress in preterm infants with bronchopulmonary dysplasia after exposure to chorioamnionitis

Inflammation is one of the main causes of preterm birth, frequently associated to intrauterine infection or chorioamnionitis. Oxidative stress is involved in preterm birth. On the one hand, reactive oxygen species are released by inflammatory cells against infection; on the other hand it is responsible of placental tissue damage after chorioamnionitis. Because of improvement in obstetric and perinatal care, survival rate in preterm births has increased, leading to changes in pathology of several processes, such as bronchopulmonary dysplasia. Bronchopulmonary dysplasia is a multifactorial entity which is consequence of multiple mechanisms, including perinatal inflammation and oxygen free radicals. Preterm newborn is very susceptible to chronic lung damage because of both, low antioxidant capacity, and exposure to high oxygen fractions during postnatal life. Modest lung oxidative stress damage after exposure to fetal endotoxin in premature newborns has been shown. Postnatal injury is needed to amplify the intrauterine inflammatory damage. Cell death induction by reactive oxygen species has been suggested as mechanism of lung damage. Several antioxidant therapies have been used in experimental studies in order to reduce or prevent bronchopulmonary dysplasia. So far, care is needed to standardize its use, because of its undesirable effects on inflammatory defense and development.

Nutrition and immunity in elderly

Aging is associated with increase in chronic disease as well as infections and associated morbidity. This is often throughout to be secondary immunosenescene. Whether this decline in immune function with aging is due to the aging process per Se or is secondary to poor health, inflammation, and other life style factors particularly suboptimal nutritional status. With aging a variety of changes are observed in the immune system, which translate into less effective innate and adaptive immune responses and in creased susceptibility to infections. Antioxidant vitamins and trace elements [vitamins C, E, selenium, copper and zinc] counteract potential damage caused by reactive oxygen species to cellular tissues and modulate immune cell function through regulation of redoxsensitive transcription factors and affect production of cytokines and prostaglandins. Adequate intake of vitamins B[6], folate, B[12], C,E, and of selenium, Zn, copper and iron supports a Th I cytokine-mediated immune response with sufficient production of proinflammatory cytokine. Vitamin A and D play important roles in both cell mediated and humoral antibody response. Nutrient supplementation is often accompanied by an improvement in immune function.
