In silico identification of 2-oxo-1,3-thiazolidine derivatives as novel inhibitor candidate of class II histone deacetylase (HDAC) in cervical cancer treatment

Cervical cancer ranks third among the most prevalent deadly cancer in women worldwide and ranks first in developing countries. It is caused by human papilloma virus (HPV) infection. Thus HDACs have become prominent inhibition target for cervical cancer treatment. In order to discover the new alternative HDAC inhibitors (HDACIs), we conducted a computer-aided drug discovery and development (CADDD) based on de novo approach. The compound library is based on 4-[(2-oxo-1,3-thiazolidin-3-yl)carbonyl] aniline. Screening of the best drug leads was evaluated from several parameters, such as docking and interaction analysis, pharmacology, in silico preclinical trial and molecular dynamics analysis. The inhibitory activity of these new designed ligands against Homo sapiens class II HDAC was determined by molecular docking simulation. Docking analysis yielded eight best ligands which have better binding affinity than the standards. Therefore, interaction analysis indicated that all best ligands performed coordination with Zn2+ cofactor in HDAC charge-relay system which are essential for HDAC inhibitory activities of these inhibitors. Pharmacology analysis and preclinical trials of these compounds including pharmacology properties, bioactivity, mutagenicity?carcinogenicity, absorption, distribution, metabolism, excretion and toxicity (ADMET) properties were done through in silico methods. Through this analysis, the best ligands meet Lipinski’s rule of five, have a better drug score than standards, and show good bioactivities, oral bioavailability and ADMET properties. All best ligands also have good synthetic accessibility and were proved to be new compounds that have never been synthesized before. Stability of HDAC?ligand complexes was also calculated through molecular dynamics (MD) simulation. Based on this simulation, complex of the best ligands with corresponding HDAC has a good stability based on RMSD (root mean square deviation) and interaction analysis. The study thus reveals eight best ligands (F, Ib14, O38, Kb17, Gd40, Aa50, Gc42 and Bb38) which have better binding affinity against human class II histone deacetylase (HDAC) through molecular docking, dynamics and interaction analysis. The best ligands were also found to have good bioactivities, oral bioavailability and ADMET properties through in silico pharmacology analysis and preclinical trial. These compounds were found to have a good synthetic accessibility; therefore they could be synthesized for further biological and clinical test.

Residual function of cystic fibrosis mutants predicts response to small molecule CFTR modulators

Treatment of individuals with cystic fibrosis (CF) has been transformed by small molecule therapies that target select pathogenic variants in the CF transmembrane conductance regulator (CFTR). To expand treatment eligibility, we stably expressed 43 rare missense CFTR variants associated with moderate CF from a single site in the genome of human CF bronchial epithelial (CFBE41o-) cells. The magnitude of drug response was highly correlated with residual CFTR function for the potentiator ivacaftor, the corrector lumacaftor, and ivacaftor-lumacaftor combination therapy. Response of a second set of 16 variants expressed stably in Fischer rat thyroid (FRT) cells showed nearly identical correlations. Subsets of variants were identified that demonstrated statistically significantly higher responses to specific treatments. Furthermore, nearly all variants studied in CFBE cells (40 of 43) and FRT cells (13 of 16) demonstrated greater response to ivacaftor-lumacaftor combination therapy than either modulator alone. Together, these variants represent 87% of individuals in the CFTR2 database with at least 1 missense variant. Thus, our results indicate that most individuals with CF carrying missense variants are (a) likely to respond modestly to currently available modulator therapy, while a small fraction will have pronounced responses, and (b) likely to derive the greatest benefit from combination therapy.

Low catalyst loadings for ligand-free copper(I)-oxide-catalyzed N-arylation of methanesulfonamide in water

A simple and practical protocol for the cross-coupling of methanesulfonamide and aryl iodides under ligand-free copper(I)-oxide-catalyzed conditions in water is reported. The method allows the preparation of a wide variety of synthetically useful N-arylated methanesulfonamides in good to excellent yields (up to 90 %) under the optimized conditions. A convenient and efficient ligand-free method using a copper(I) oxide catalyst at 130 C in water was developed for the N-arylation of methanesulfonamide with aryl iodides. A variety of functionalized aliphatic and cyclic sulfonamides were coupled with different substituted aryl halides to give the corresponding N-arylated products in good to excellent yields under the optimized conditions.

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.

The application of anthraquinone-based triazenes as equivalents of diazonium salts in reaction with methylene active compounds

A series of polyfunctionalized anthraquinonehydrazones have been prepared using azo-coupling reaction between anthraquinone-based triazenes and methylene active compounds in acetic acid without a catalyst. The structures of new synthesized compounds were confirmed by their IR, LCMS,1H and 13C NMR spectroscopic data. Some of the synthesized compounds were screened for their in vitro anticancer activity according to US NCI protocols. Biological screening data led to the identification of 1-{N?-[3-(4-hydroxyphenyl)-4-oxo-2-thioxothiazolidin-5-ylidene]hydrazino}anthraquinone 3.4 as having antitumor activity on the non-small cell lung cancer NCI-H460 (GP = 13.25%) and colon cancer HCT-116 (GP = 13.69%) cell lines.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 7025-19-6 is helpful to your research. Computed Properties of C6H7NO3S2

A visible-light-promoted oxo-sulfonylation of ynamides with sulfonic acids is reported, giving rise to a collection of functionalized alpha-sulfonylated amides in a straightforward manner. The reaction proceeds sequentially through a cascade of electrophilic addition and photoinduced sulfonyl radical-sustained skeleton rearrangement. The high atom economy, mild reaction conditions, and wide substrate scope comprised the merits of this synthetic transformation.
