Discovery of (S)-3-(3-(3,5-Dimethyl-1 H-pyrazol-1-yl)phenyl)-4-((R)-3-(2-(5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)ethyl)pyrrolidin-1-yl)butanoic Acid, a Nonpeptidic alphavbeta6 Integrin Inhibitor for the Inhaled Treatment of Idiopathic Pulmonary Fibrosis

A series of 3-aryl(pyrrolidin-1-yl)butanoic acids were synthesized using a diastereoselective route, via a rhodium catalyzed asymmetric 1,4-addition of arylboronic acids in the presence of (R)-BINAP to a crotonate ester to provide the (S) absolute configuration for the major product. A variety of aryl substituents including morpholine, pyrazole, triazole, imidazole, and cyclic ether were screened in cell adhesion assays for affinity against alphavbeta1, alphavbeta3, alphavbeta5, alphavbeta6, and alphavbeta8 integrins. Numerous analogs with high affinity and selectivity for the alphavbeta6 integrin were identified. The analog (S)-3-(3-(3,5-dimethyl-1H-pyrazol-1-yl)phenyl)-4-((R)-3-(2-(5,6,7,8-tetrahydro-1,8-naphthyridin-2-yl)ethyl)pyrrolidin-1-yl)butanoic acid hydrochloride salt was found to have very high affinity for alphavbeta6 integrin in a radioligand binding assay (pKi = 11), a long dissociation half-life (7 h), very high solubility in saline at pH 7 (>71 mg/mL), and pharmacokinetic properties commensurate with inhaled dosing by nebulization. It was selected for further clinical investigation as a potential therapeutic agent for the treatment of idiopathic pulmonary fibrosis.

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.Recommanded Product: Tetrahydro-2H-pyran-4-ol, you can also check out more blogs about2081-44-9

Triazolopyridazine LRRK2 kinase inhibitors

Leucine-rich repeat kinase 2 (LRRK2) has been implicated in the pathogenesis of Parkinson’s disease (PD). Inhibition of LRRK2 kinase activity is a therapeutic approach that may lead to new treatments for PD. Herein we report the discovery of a series of [1,2,4]triazolo[4,3-b]pyridazines that are potent against both wild-type and mutant LRRK2 kinase activity in biochemical assays and show an unprecedented selectivity towards the G2019S mutant. A structural rational for the observed selectivity is proposed.

One-pot multi-component synthesis and solid state structures of functionally rich polyether macrocycles

Densely functionalized polyether macrocycles can be prepared in one pot in yields up to 60% by the rhodium(II)-catalyzed decomposition of methyl diazoacetoacetate in the presence of a variety of substituted or unsaturated 5- and 6-membered ring cyclic ethers. A comprehensive analysis of the solid state conformations of the macrocyclic geometries is detailed as well as novel mechanistic insights about the multi-component condensation reaction. Copyright

BiCl3: A versatile catalyst for the tetrahydropyranylation and depyranylation of 1,2,3, allylic, benzylic alcohols, and symmetric diols

Bismuth trichloride as mild reagent, has been found to be a worthful catalyst for tetrahydropyranylation of 1,2,3, allylic, benzylic alcohols, and symmetric di-ols. At room temperature the reagent THP(3,4-dihydro-2H-pyran) was successfully employed as pyranylating agent in presence of BiCl3catalyst without the use of a solvent and the yields of the products were found to be 90-96%. Further, the depyranylation of alcohols was achieved in quantitative yield by simple addition of MeOH using the same catalyst. The developed method was showed good chemo-selectivity in symmetrical diols for mono THP protection.
