Preparation method of minodronic acid key intermediate
The invention belongs to the technical field of drug synthesis, and provides a preparation method of a minodronic acid key intermediate. The method comprises the following steps: reacting ethyl 4-chloroacetoacetate with an ammonia organic solution to obtain a compound V, and reacting the compound V with a compound IV under the catalysis of a [Cu] catalyst to obtain a compound III imidazo[1,2-a]pyridine-3-acetamide; and hydrolyzing the compound III with concentrated hydrochloric acid to obtain a compound II imidazo[1,2-a]pyridine-3-acetic acid. The method has the advantages that the reaction conditions are simple, the raw material utilization degree is high, the yield is high, the purity is high, the pollution to the environment is small, and the method is suitable for industrial production.

METHODS FOR HAIR FOLLICLE STEM CELL PROLIFERATION
The present invention relates to compositions of minoxidil and Sonic Hedgehog (Shh) pathway activators and optionally, Wnt agonists and methods of using them to induce self-renewal of hair follicle stem cells, including inducing the hair follicle stem cells to proliferate while maintaining, in the daughter cells, the capacity to differentiate into hair follicle epithelial cells.

Practical and scalable preparation of Minodronic acid and Zolpidem from 2-chloroimidazole[1,2-a]pyridines
Practical and scalable procedures for Minodronic acid and Zolpidem are developed with short reaction sequences from 2-aminopyridines and maleic anhydride, respectively. The new procedures avoid column chromatography for the purification in all synthetic steps. Key aspects of this development involve reductive hydrodechlorination and Suzuki coupling reaction of 2-chloroimidazole[1,2-a]pyridines, and their application towards synthesis of the two drugs is also addressed.

The development of potent and selective bisarylmaleimide GSK3 inhibitors
Many 3-aryl-4-(1,2,3,4-tetrahydro[1,4]diazepino[6,7,1-hi]indol-7-yl) maleimides exhibit potent GSK3 inhibitory activity (50), although few show significant selectivity (>100 ×) versus CDK2, CDK4, or PKCβII. However, combining 3-(imidazo[1,2-a]pyridin-3-yl), 3-(pyrazolo[1,5-a]pyridin-3-yl) or aza-analogs with a 4-(2-acyl-(1,2,3,4- tetrahydro[1,4]diazepino[6,7,1-hi]indol -7-yl)) group on the maleimide resulted in very potent inhibitors of GSK3 (≤5 nM) with >160 to >10,000-fold selectivity versus CDK2/4 and PKCβII. These compounds also inhibited tau phosphorylation in cells and were effective in lowering plasma glucose in a rat model of type 2 diabetes (ZDF rat).

Substituted 3-imidazo[1,2-a]pyridin-3-yl-4-(1,2,3,4-tetrahydro-[1,4] diazepino-[6,7,1-hi]indol-7-yl)pyrrole-2,5-diones as highly selective and potent inhibitors of glycogen synthase kinase-3
Glycogen synthase kinase-3 (GSK3) is involved in signaling from the insulin receptor. Inhibitors of GSK3 are expected to effect lowering of plasma glucose similar to insulin, making GSK3 an attractive target for the treatment of type 2 diabetes. Herein we report the discovery of a series of potent and selective GSK3 inhibitors. Compounds 7-12 show oral activity in an in vivo model of type II diabetes, and 9 and 12 have desirable PK properties.
