Delivery of peptide and protein drugs over the blood-brain barrier

Peptide and protein (P/P) drugs have been identified as showing great promises for the treatment of various neurodegenerative diseases. A major challenge in this regard, however, is the delivery of P/P drugs over the blood-brain barrier (BBB). Intense research over the last 25 years has enabled a better understanding of the cellular and molecular transport mechanisms at the BBB, and several strategies for enhanced P/P drug delivery over the BBB have been developed and tested in preclinical and clinical-experimental research. Among them, technology-based approaches (comprising functionalized nanocarriers and liposomes) and pharmacological strategies (such as the use of carrier systems and chimeric peptide technology) appear to be the most promising ones. This review combines a comprehensive overview on the current understanding of the transport mechanisms at the BBB with promising selected strategies published so far that can be applied to facilitate enhanced P/P drug delivery over the BBB.

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.Related Products of 19771-63-2

Discovery, synthesis, and structure-activity relationship development of a series of N -4-(2,5-dioxopyrrolidin-1-yl)phenylpicolinamides (VU0400195, ML182): Characterization of a novel positive allosteric modulator of the metabotropic glutamate receptor 4 (mGlu4) with oral efficacy in an antiparkinsonian animal model

There is an increasing amount of literature data showing the positive effects on preclinical antiparkinsonian rodent models with selective positive allosteric modulators of metabotropic glutamate receptor 4 (mGlu4). However, most of the data generated utilize compounds that have not been optimized for druglike properties, and as a consequence, they exhibit poor pharmacokinetic properties and thus do not cross the blood-brain barrier. Herein, we report on a series of N-4-(2,5-dioxopyrrolidin-1-yl) phenylpicolinamides with improved PK properties with excellent potency and selectivity as well as improved brain exposure in rodents. Finally, ML182 was shown to be orally active in the haloperidol induced catalepsy model, a well-established antiparkinsonian model.

4-Thiazolidinone coumarin derivatives as two-component NS2B/NS3 DENV flavivirus serine protease inhibitors: synthesis, molecular docking, biological evaluation and structure?activity relationship studies

A series of novel 4-thiazolidinone inhibitors SKYa?SKYg, containing coumarin as a core structure were synthesized via facile and efficient method. The structures of the synthesized compounds were established by extensive spectroscopic studies (FT IR, 1D NMR, 2D NMR, LC?MS) and elemental analysis. All the synthesized hybrids were further evaluated for their potential as anti-tubercular agents against Mycobacterium tuberculosis H37Rv ATCC 25618, and anti-bacterial agents against Escherichia coli, Enterobacter aerogenes, Salmonella typhi, Streptococcus pneumoniae and Staphylococcus aureus. Interestingly, the hybrids displayed potent bioactivity. However, compounds SKYc, SKYd, and SKYe appeared to be more effective against the tested bacterial strains, among which compound SKYb showed the highest inhibition against all the bacterial strains ranging from 41 to 165?mug/mL, as compared to the standards, streptomycin, kanamycin and vancomycin. Moreover, derivative SKYa was found to be the strongest against M. tuberculosis (83?mug/mL). Additionally, the anti-dengue potential of the coumarin hybrids as two-component NS2B/NS3 DENV flavivirus serine protease inhibitors was calculated using computational molecular docking approach, with reference to the standards 4-hydroxypanduratin, panduratin and ethyl 3-(4-(hydroxymethyl)-2-methoxy-5-nitrophenoxy)propanoate with DS of ? 3.379, ? 3.189 and ? 3.381, respectively. The docking results revealed that the synthesized hybrids exhibited potent anti-dengue activity among which compounds SKYf, SKYd, SKYc and SKYe were found to be the best ones with docking scores of ? 4.014, ? 3.964, ? 3.905 and ? 3.889. In summary, we discovered 4-thiazolidinone coumarin derivatives as a new scaffold that may eventually yield useful compounds in the treatment of bacterial and viral infections.[Figure not available: see fulltext.].

Synthesis and evaluation of thiazolidine-2,4-dione/benzazole derivatives as inhibitors of protein tyrosine phosphatase 1B (PTP-1B): Antihyperglycemic activity with molecular docking study

This work presents the synthesis of two hybrid compounds (1 and 2) with thiazolidine-2,4-dione structure as a central scaffold which were further screened in combo (in vitro as PTP-1B inhibitors, in vivo antihyperglycemic activity, in silico toxicological profile and molecular docking). Compound 1 was tested in the enzymatic assay showing an IC50 = 9.6 ¡À 0.5 muM and compound 2 showed about a 50% of inhibition of PTP-1B at 20 muM. Therefore, compound 1 was chosen to test its antihyperglycemic effect in a rat model for non-insulin-dependent diabetes mellitus (NIDDM), which was determined at 50 mg/kg in a single dose. The results indicated that compound showed a significant decrease of plasma glucose levels that reached 34%, after a 7 h post-administration. Molecular docking was employed to study the inhibitory properties of thiazolidine-2,4-dione derivatives against Protein Tyrosine Phosphatase 1B (PDB ID: 1c83). Concerning to the two binding sites in this enzyme (sites A and B), compound 1 has shown the best docking score, which indicates the highest affinity. Finally, compounds 1 and 2 have demonstrated an in silico satisfactory pharmacokinetic profile. This shows that it could be a very good candidate or leader for new series of compounds with this central scaffold.

Circulating levels of adipose tissue-derived inflammatory factors in elderly diabetes patients with carotid atherosclerosis: A retrospective study

Background: Inflammation has been recognized as a key feature of both type 2 diabetes mellitus (T2DM) and atherosclerosis. However, the relationships between circulating levels of novel adipose tissue-derived inflammatory factors, including resistin, vaspin, and visfatin, and the severity of atherosclerosis have not been determined. Moreover, the associations between these inflammatory factors and obesity and insulin resistance in elderly patients remain to be clarified. Methods: A cross-sectional study of 256 elderly patients with T2DM admitted in our center was performed. Baseline circulating levels of resistin, vaspin and visfatin were measured with enzyme-linked immunosorbent assays. Ultrasonic evaluations of the carotid arteries of the patients were performed to reflect the severity of systemic atherosclerosis. Patients were classified as having mild, moderate, or severe atherosclerosis according to the results of carotid ultrasonic examination. Circulating levels of the inflammatory factors listed above also were correlated with body mass index (BMI) and homeostasis model assessment of insulin resistance (HOMA-IR). Results: With more severe carotid atherosclerosis, circulating levels of resistin (mild: 2.01 ¡À 0.23; moderate: 2.89 ¡À 1.01; severe: 3.12 ¡À 1.12; p < 0.05) and visfatin (mild: 11.63 ¡À 7.48; moderate: 15.24 ¡À 2.19; severe: 17.54 ¡À 2.98; p < 0.05) gradually increased, while level of vaspin decreased (mild: 317 ¡À 23.12; moderate: 269 ¡À 32.12; severe: 229 ¡À 14.24; p < 0.05). Subsequent results of Pearson coefficient analyses indicated that all of the tested adipose tissue-derived inflammatory factors were positively correlated with the BMI and HOMA-IR of the patients (all p < 0.05), even after adjustment for hs-CRP. Conclusions: The adipose tissue-derived inflammatory factors resistin, vaspin and visfatin may be involved in the pathogenesis of atherosclerosis in elderly T2DM patients. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2682-49-7, help many people in the next few years.Application of 2682-49-7
