  zebrafish (Danio rerio) toxicity models. 3,4-Dihydroquinazolin-4-ones 9q and 9w were considered the lead compounds of these series of molecules with MIC values of 0.24 μM and 0.94 μM against M. tuberculosis H37Rv, respectively. Taken together, these data indicate that this class of compounds may furnish candidates for future development of novel anti-TB drugs.

  We have discovered a novel class of endothelin (ET) receptor antagonists through pharmacophore analysis of the existing non-peptide ET antagonists. On the basis of this analysis, we determined that a pyrrolidine ring might replace the indan ring in SE 209670. The resultant compounds were readily prepared and amenable to extensive SAR studies. Thus a series of N-substituted trans,trans-2-(4-methoxyphenyl)-4-(1,3-benzodioxol-5-yl) pyrrolidine-3-carboxylic acids (8) have been synthesized and evaluated for binding at ET(A) and ET(B) receptors. Compounds with N-acyl and simple N-alkyl substituents had weak activity. Compounds with N-alkyl substituents containing ethers, sulfoxides, or sulfones showed increased activity. Much improved activity resulted from compounds where the N-substituents were acetamides. Compound 17u (A-127722) with the N,N-dibutylacetamide substituent is the best of the series. It has an IC50 = 0.36 nM for inhibition of ET-1 radioligand binding at the ETA(A) receptor, with a 1000-fold selectivity for the ET(A) vs the ET(B) receptor. It is also a potent inhibitor (IC50 = 0.16 nM) of phosphoinositol hydrolysis stimulated by ET-1, and it antagonized the ET-l-induced contraction of the rabbit aorta with a pA(2) = 9.20. The compound has 70% oral bioavailability in rats.
• Synthesis of γ-lactams via Ru(II)–Pheox-catalyzed regioselective intramolecular Csp3–H insertion of diazoacetamides

  Herein, γ-lactam derivatives are obtained in high yield via highly regioselective intramolecular Csp3–H insertion reactions of α-diazoacetamides catalyzed by a rac-Ru(II)–Pheox complex. The catalytic system is applicable to a wide range of diazoacetamides under mild conditions to produce the corresponding γ-lactams.
