phosphatidylinositol 3-kinases (PI3Ks) is a very promising approach for cancer treatment. This manuscript describes the design, synthesis, in vitro pharmacological profile, and molecular modeling of a novel class of N-acylhydrazone (NAH) derivatives that act as HDAC6/8 and PI3Kα dual inhibitors. The surprising selectivity for PI3Kα may be related to differences in the conformation in the active site
An efficient one-pot palladium-catalyzed reaction for the synthesis of diazoles from readily available hydrazides and aryl halide via isocyanide insertion/cyclization sequence has been developed.
Provided herein are compounds of the formula (1):
as well as pharmaceutically acceptable salts thereof, wherein the substituents are as those disclosed in the specification. These compounds, and the pharmaceutical compositions containing them, are useful for the treatment of diseases such as, for example, obesity, type II diabetes mellitus and metabolic syndrome.
The borrowing hydrogen strategy has been applied in the synthesis of nonsymmetric N,N-dialkylated acyl hydrazides via a tandemthree-componentreaction catalyzed by a phosphine free diaminocyclopentadienone ruthenium tricarbonyl complex. This strategy represents the first direct one-pot approach to nonsymmetric functionalized acyl hydrazides. Different aromatic acyl hydrazides underwent dialkylation

The present invention relates to a novel azole derivative as an apelin receptor agonist and a method for treating cardiovascular disease, diabetic disease, renal disease, hypertension, and arteriosclerosis, etc., using the same. The present invention provides a compound represented by formula (I) or a pharmacologically acceptable salt thereof wherein X1 represents -N= or -CH=, X2 represents -CH= or -N=, R1 and R2 each represent a C1 to C6 alkoxy group or the like, R3 represents a heteroaryl group (the heteroaryl group is optionally substituted by a methyl group or the like) or the like, and R4 represents a C1 to C6 alkylthio group or a C2 to C6 alkenyl group (the C1 to C6 alkylthio group and the C2 to C6 alkenyl group are each optionally substituted by one carboxy group or the like) or the like.
