Spectroscopic investigations of the interactions of potential antitumor amino-thiazolidinone platinum (II) compounds with human serum albumin

An amino-thiazolidinone platinum(II) compound which could rapidly induce apoptosis in tumor cells and showed no cross resistance against the cisplatin-resistant cells, was firstly to study of protein-drug interactions. To investigate the potential of Pt(II) compounds as therapeutic drugs, two Pt(II) complexes (1 and 2) were explored the influences based on their interaction in vitro with human serum albumin (HSA) by fluorescence spectrometry and UV?Vis absorption. The binding interactions of two compounds with HSA results in the formation of corresponding HSA-drug complexes, van der Waals forces and hydrogen bonding played key roles in stabilizing these complexes. Both of two compounds were through a dynamic quenching mechanism, this dynamic reversible binding process was of great significance to the equilibrium of drug concentrations in vivo, which ensured that the internal environment of the organism was in a relatively stable state.

Current status and future prospects of Marine Natural Products (MNPs) as antimicrobials

The marine environment is a rich source of chemically diverse, biologically active natural products, and serves as an invaluable resource in the ongoing search for novel antimicrobial compounds. Recent advances in extraction and isolation techniques, and in state-of-the-art technologies involved in organic synthesis and chemical structure elucidation, have accelerated the numbers of antimicrobial molecules originating from the ocean moving into clinical trials. The chemical diversity associated with these marine-derived molecules is immense, varying from simple linear peptides and fatty acids to complex alkaloids, terpenes and polyketides, etc. Such an array of structurally distinct molecules performs functionally diverse biological activities against many pathogenic bacteria and fungi, making marine-derived natural products valuable commodities, particularly in the current age of antimicrobial resistance. In this review, we have highlighted several marine-derived natural products (and their synthetic derivatives), which have gained recognition as effective antimicrobial agents over the past five years (2012?2017). These natural products have been categorized based on their chemical structures and the structure-activity mediated relationships of some of these bioactive molecules have been discussed. Finally, we have provided an insight into how genome mining efforts are likely to expedite the discovery of novel antimicrobial compounds.

Biased signaling and allosteric modulation at the FSHR

Knowledge on G protein-coupled receptor (GPCRs) structure and mechanism of activation has profoundly evolved over the past years. The way drugs targeting this family of receptors are discovered and used has also changed. Ligands appear to bind a growing number of GPCRs in a competitive or allosteric manner to elicit balanced signaling or biased signaling (i.e., differential efficacy in activating or inhibiting selective signaling pathway(s) compared to the reference ligand). These novel concepts and developments transform our understanding of the follicle-stimulating hormone (FSH) receptor (FSHR) biology and the way it could be pharmacologically modulated in the future. The FSHR is expressed in somatic cells of the gonads and plays a major role in reproduction. When compared to classical GPCRs, the FSHR exhibits intrinsic peculiarities, such as a very large NH2-terminal extracellular domain that binds a naturally heterogeneous, large heterodimeric glycoprotein, namely FSH. Once activated, the FSHR couples to Galphas and, in some instances, to other Galpha subunits. G protein-coupled receptor kinases and beta-arrestins are also recruited to this receptor and account for its desensitization, trafficking, and intracellular signaling. Different classes of pharmacological tools capable of biasing FSHR signaling have been reported and open promising prospects both in basic research and for therapeutic applications. Here we provide an updated review of the most salient peculiarities of FSHR signaling and its selective modulation.

Structural features and inhibitors of bromodomains

Bromodomains are conserved structural modules responsible for recognizing acetylated-lysine residues on histone tails and other transcription-associated proteins, such as transcription factors and co-factors. Owing to their important functions in the regulation of ordered gene transcription in chromatin, bromodomains of the BET family proteins have recently been shown as druggable targets for a wide array of human diseases, including cancer and inflammation. Here we review the structural and functional features of the bromodomains and their small-molecule inhibitors. Additional new insights provided herein highlight the landscape of the ligand binding sites in the bromodomains that will hopefully facilitate further development of new inhibitors with optimal affinity and selectivity.

Synthesis of novel phenyl substituted dibenzonaphthyridines

The reaction of 2,4-dichloroquinolines with 2-amino-5-chlorobenzophenone yielded 2-[(2-benzoyl-4-chlorophenyl) amino]-4-chloroquinolines which with sodium methoxide afforded 2-[(2-benzoyl-4-chlorophenyl)amino]-4- methoxyquinolines. These on PPA-catalysed cyclisation gave 2-chloro-12- phenyldibenzo[b,g][1,8]naphthyridin-11(6H)-ones. Temperature differences for the formation of the final products were due to the in situ formation of the 2-[(2-benzoyl-4-chlorophenyl)amino]quinolin-4-ones from the chloro and methoxy intermediates. The dibenzonaphthyridin-11-ones were N-methylated at N(6); a methyl group at C(7) was found to hinder the methylation reaction sterically, when a considerably longer reaction time was needed.

Protection against acetaminophen-induced hepatotoxicity by L-CySSME and its N-acetyl and ethyl ester derivatives.

We have recently observed that S-(2-hydroxyethylmercapto)-L-cysteine (L-CySSME), the mixed disulfide of L-cysteine and 2-mercaptoethanol, prevented cataracts induced in mice by acetaminophen (ACP) by functioning as a prodrug of L-cysteine and protecting the liver. This prompted the evaluation of the more lipophilic N-acetyl (Ac-CySSME) and ethyl ester (Et-CySSME) derivatives of L-CySSME as proprodrug forms, as well as the “D” enantiomer, as hepatoprotective agents. Serum ALT levels were measured at 24 hours after a toxic but nonlethal dose of ACP that insured 48 hour survival of the animals. Since the increases in ALT produced were highly variable (even after log transformation) and complicated the statistical analyses, we calculated confidence intervals for the mean ALT levels for each treatment group. This enabled comparisons to be made of the efficacy of L-CySSME as well as Ac-CySSME and Et-CySSME with other representative prodrugs of L-cysteine, namely, 2(RS)-methylthiazolidine-4(R)-carboxylic acid (MTCA), L-2-oxothiazolidine-4-carboxylic acid (OTCA), and N-acetyl-L-cysteine (NAC), in protecting the liver. It was shown that L-CySSME and MTCA administered intraperitoneally at 2.5 mmol/kg were superior to the other cysteine prodrugs at equimolar doses in protecting mice from hepatotoxicity elicited by a 400 mg/kg (2.65 mmol/kg) dose of ACP given i.p. 30 minutes prior to the prodrugs. The “D” form of CySSME was totally without protective effect. Oral doses of the prodrugs even at 2x the i.p. dose were less effective, although MTCA was the most protective.

Synthesis, characterization and acute anti-inflammatory evaluation of new mefenamic acid derivatives having 4-thiazolidinone nucleus

Mefenamic acid (MA) is one of the non-steroidal anti-inflammatory drugs, it is widely used probably due to having both anti-inflammatory and analgesic activity, the main side effects of mefenamic acid include gastrointestinal tract (GIT) disturbance mainly diarrhea, peptic ulceration, and gastric bleeding. The analgesic effects of NSAIDs are probably linked to COX-2 inhibition, while COX-1 inhibition is the major cause of this classic adverse effects. Introduction of thiazolidinone may lead to the increase in the bulkiness leads to the preferential inhibition of COX-2 rather than COX-1 enzyme. The study aimed to synthesize derivatives of mefenamic acid with more potency and to decrease the drug’s potential side effects, new series of 4-thiazolidinone derivatives of mefenamic acid were synthesized IVa-g. The synthetic procedures for target compounds and their intermediates are designed to be as follows: acylation of secondary amine of mefenamic acid by chloroacetylchloride to produce compound (I), then reaction between compound (I) and hydrazine hydrate to form hydrazine derivative of mefenamic acid (compound II). After that, Schiff base formation by addition of seven benzaldehyde derivatives and finally, cyclization in presence of thioglycolic acid to form 4-thiazolidinone heterocyclic ring. The characterization of the titled compounds has been established on the basis of their spectral FTIR, 1HNMR data, and by measurements of their physical properties. In vivo acute anti-inflammatory effect of the synthesized compounds was evaluated in rats using egg-white induced edema model of inflammation. The tested compounds and the reference drug produced significant reduction of paw edema with respect to the effect of dimethyl sulfoxide 10%v/v (control group). Compound IVe showed more potent effect than mefenamic acid at 240-300 min, while at time 300 min, compounds IVa and IVd exhibit more potent anti-inflammatory effect than mefenamic acid (50mg/kg, i.p.) as they reduced paw edema significantly more than mefenamic acid at mentioned intervals (p<0.05) . On the other hand compound IVc exhibited lower anti-inflammatory effect. One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Computed Properties of C3H5NOS, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 2682-49-7
