L-Oxothiazolidine 4-carboxylate pretreatment of isolated human peripheral blood lymphocytes reduces sulfur mustard cytotoxicity

Sulfur mustard (HD, mustard gas) is a vesicant chemical warfare agent for which there is no specific medical countermeasure. A potential approach to combating the debilitating effects of this agent is the use of compounds that can react with this material before it interacts with critical macromolecules. Glutathione (GSH), a tripeptide that exists in high concentrations in cells, reacts with HD and is involved in HD detoxification. Pretreatment of human peripheral blood lymphocytes (PBL) with 10 mmol/L L-oxothiazolidine-4-carboxylate (OTC), a ‘masked’ cysteine precursor, increased intracellular glutathione levels 25-50% over control values. Pretreated PBL were harvested, washed, and exposed to 10, 50, or 100 mumol/L HD. Flow cytometry was used to measure cytotoxicity by propidium iodide uptake. Pretreatment of PBL with OTC led to small decreases in cytotoxicity after HD exposure. However, treatment of cells with OTC after HD exposure was not beneficial. Compounds that can modulate GSH levels within the cell may help to reduce the cytotoxicity of HD when used as a pretreatment.

Discovery of Ziresovir as a Potent, Selective, and Orally Bioavailable Respiratory Syncytial Virus Fusion Protein Inhibitor

Ziresovir (RO-0529, AK0529) is reported here for the first time as a promising respiratory syncytial virus (RSV) fusion (F) protein inhibitor that currently is in phase 2 clinical trials. This article describes the process of RO-0529 as a potent, selective, and orally bioavailable RSV F protein inhibitor and highlights the in vitro and in vivo anti-RSV activities and pharmacokinetics in animal species. RO-0529 demonstrates single-digit nM EC50 potency against laboratory strains, as well as clinical isolates of RSV in cellular assays, and more than one log viral load reduction in BALB/c mouse model of RSV viral infection. RO-0529 was proven to be a specific RSV F protein inhibitor by identification of drug resistant mutations of D486N, D489V, and D489Y in RSV F protein and the inhibition of RSV F protein-induced cell-cell fusion in cellular assays.

Assessment of substrate-dependent ligand interactions at the organic cation transporter OCT2 using six model substrates s

Organic cation transporter (OCT) 2 mediates the entry step for organic cation secretion by renal proximal tubule cells and is a site of unwanted drug-drug interactions (DDIs). But reliance on decision tree-based predictions of DDIs at OCT2 that depend on IC50 values can be suspect because they can be influenced by choice of transported substrate; for example, IC50 values for the inhibition of metformin versus MPP transport can vary by 5- to 10-fold. However, it is not clear whether the substrate dependence of a ligand interaction is common among OCT2 substrates. To address this question, we screened the inhibitory effectiveness of 20 mM concentrations of several hundred compounds against OCT2-mediated uptake of six structurally distinct substrates: MPP, metformin, N,N,N-trimethyl-2-[methyl(7-nitrobenzo[c][1,2,5]-oxadiazol-4-yl)amino]ethanaminium (NBD-MTMA), TEA, cimetidine, and 4-4-dimethylaminostyryl-N-methylpyridinium (ASP). Of these, MPP transport was least sensitive to inhibition. IC50 values for 20 structurally diverse compounds confirmed this profile, with IC50 values for MPP averaging 6-fold larger than those for the other substrates. Bayesian machine-learning models of ligand-induced inhibition displayed generally good statistics after cross-validation and external testing. Applying our ASP model to a previously published large-scale screening study for inhibition of OCT2-mediated ASP transport resulted in comparable statistics, with approximately 75% of ?active? inhibitors predicted correctly. The differential sensitivity of MPP transport to inhibition suggests that multiple ligands can interact simultaneously with OCT2 and supports the recommendation that MPP not be used as a test substrate for OCT2 screening. Instead, metformin appears to be a comparatively representative OCT2 substrate for both in vitro and in vivo (clinical) use.

First catalytic enantioselective synthesis of P-stereogenic phosphoramides via kinetic resolution promoted by a chiral bicyclic imidazole nucleophilic catalyst

A novel method toward the synthesis of P-stereogenic organophosphorus compounds via kinetic resolution by a catalytic asymmetric phosphorylation through P-N bond formation has been developed. Using a chiral bicyclic imidazole nucleophilic catalyst, chiral phosphoramide compounds were prepared in high conversions and with moderate enantioselectivity. This is also the first example of the catalytic asymmetric synthesis of chiral phosphoramide compounds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 2682-49-7, you can also check out more blogs about2682-49-7

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.

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.

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.

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.

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.
