Chiral pyrrolidinebisphosphine ligands, (2S-cis)-BCPM and (2S-cis)-BCPP, bearing two different types of phosphino groups, a dicyclohexylphosphino group and a diphenylphosphino group, were designed and prepared on the basis of our design concept for developing highly efficient ligands. The validity of the concept was confirmed experimentally in the asymmetric hydrogenation of ketopantolactone using neutral rhodium(I) complexes of BCPM. BCPP, BPPM, and BCCP. The rhodium(I) complex of (2S-cis)-BCPM was found to be the most effective catalyst (substrate/catalyst >ca. 104, >90% ee (R)).

The design and synthesis of a series of 11,12-cyclic carbamate derivatives of 6-O-methylerythromycin A that are novel, nonpeptide LHRH antagonists, is described. The macrolide antagonist 1, discovered during a screen of our chemical repository, was compared to a macrocyclic peptide antagonist 2 using molecular modeling, thus providing a model for the design of more potent antagonists. Medicinal chemistry efforts to find a replacement for cladinose at position 3 of the erythronolide core provided a series of oxazolidinone carbamates that were equally as active as the cladinose-containing parent macrolides. The descladinose LHRH antagonist 14 has 1-2 nM affinity for both rat and human LHRH receptors and is a potent inhibitor of LH release (pA 2 = 8.76) in vitro. In vivo, 14 was found to produce a dose-dependent suppression of LH in male castrate rats via both iv and po dosing.

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.Product Details of 89364-31-8, you can also check out more blogs about89364-31-8

As experimental evaluation of the safety of nanoparticles (NPs) is expensive and time-consuming, computational approaches have been found to be an efficient alternative for predicting the potential toxicity of new NPs before mass production. In this background, we have developed here a regression-based nano quantitative structure-activity relationship (nano-QSAR) model to establish statistically significant relationships between the measured cellular uptakes of 109 magnetofluorescent NPs in pancreatic cancer cells with their physical, chemical, and structural properties encoded within easily computable, interpretable and reproducible descriptors. The developed model was rigorously validated internally as well as externally with the application of the principles of Organization for Economic Cooperation and Development (OECD). The test for domain of applicability was also carried out for checking reliability of the predictions. Important fragments contributing to higher/lower cellular uptake of NPs were identified through critical analysis and interpretation of the developed model. Considering all these identified structural attributes, one can choose or design safe, economical and suitable surface modifiers for NPs. The presented approach provides rich information in the context of virtual screening of relevant NP libraries.

A pharmacophore-based search led to the identification of thiazolopyridine ureas as a novel scaffold with antitubercular activity acting through inhibition of DNA Gyrase B (GyrB) ATPase. Evaluation of the binding mode of thiazolopyridines in a Mycobacterium tuberculosis (Mtb) GyrB homology model prompted exploration of the side chains at the thiazolopyridine ring C-5 position to access the ribose/solvent pocket. Potent compounds with GyrB IC 50 ? 1 nM and Mtb MIC ? 0.1 muM were obtained with certain combinations of side chains at the C-5 position and heterocycles at the C-6 position of the thiazolopyridine core. Substitutions at C-5 also enabled optimization of the physicochemical properties. Representative compounds were cocrystallized with Streptococcus pneumoniae (Spn) ParE; these confirmed the binding modes predicted by the homology model. The target link to GyrB was confirmed by genetic mapping of the mutations conferring resistance to thiazolopyridine ureas. The compounds are bactericidal in vitro and efficacious in vivo in an acute murine model of tuberculosis.

The double Mannich reaction of cyclic beta-keto esters with bis-(alkoxymethyl)alkylamines provides an efficient and versatile method for the construction of azabicyclo[3.3.1]nonanes and azabicyclo[3.2.1]octanes. The optimum conditions for efficient reaction involve use of the activator trichloromethylsilane in acetonitrile as solvent at ambient temperature. The utility of this synthetic method is further demonstrated by the facile synthesis of several AE ring analogues 39, 42 of the alkaloid methyllycaconitine by appendage of the key N-(methylsuccininimido)anthranilate pharmacophore to the N-(3-phenylpropyl)-substituted double Mannich adducts 18, 27.

A series of lactone 1,4-dihydroquinoline derivatives 4 (4 and 4aa?4cm) was screened for in vitro antileishmanial activity against the promastigote form of Leishmania (Leishmania) amazonensis. Screening results indicate that all of the synthesized compounds significantly reduced the growth of promastigote forms of promastigotes of L. (L.) amazonensis. The cytotoxicity of the most active compounds was also measured on peritoneal macrophage cells. Compounds 4ah and 4bn showed better activities than other derivatives with IC50 values of 6.22 and 9.05 muM, respectively, with selectivity index 22 and 15 times less toxicity to macrophages cells than to parasites, respectively. The experimental data propose that the compounds may be further investigated against amastigote forms and may contribute to the search of new candidates drugs for treatment of cutaneous leishmaniasis.
