2-Aminobenzo[b]thiophenecarboxylic esters from 3-hydroxy-2-nitro-1-thiochromone
Eiden,Felbermeir
, p. 675 - 680 (1984)
3-Hydroxy-2-nitro-1-thiochromone (1b), when mixed with basis in alcoholic solution, yields the 2-nitro-benzothiophene-3-carboxylates 4a and 4b as well as the 2-amino-3-benzothiophene-3-carboxylates 11a and 11b. Under the same conditions, 3-methoxy-2-nitro-1-thiochromone (1c) yields 3-amino-2-nitro-1-thiochromone (12). Compound 1b reacts with morpholine in dioxane to give 2-nitro-benzothiophene-3-carboxamide (10).
Development of thieno- and benzopyrimidinone inhibitors of the Hedgehog signaling pathway reveals PDE4-dependent and PDE4-independent mechanisms of action

From a high content in vivo screen for modulators of developmental patterning in embryonic zebrafish, we previously identified eggmanone (EGM1, 3) as a Hedgehog (Hh) signaling inhibitor functioning downstream of Smoothened. Phenotypic optimization studies for in vitro probe development utilizing a Gli transcription-linked stable luciferase reporter cell line identified EGM1 analogs with improved potency and aqueous solubility. Mechanistic profiling of optimized analogs indicated two distinct scaffold clusters: PDE4 inhibitors able to inhibit downstream of Sufu, and PDE4-independent Hh inhibitors functioning between Smo and Sufu. Each class represents valuable in vitro probes for elucidating the complex mechanisms of Hh regulation.

A simple method for the preparation of alkyl 2-aminobenzo[b]thiophene-3-carboxylates is described. Alkyl 2-amino-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylates, generated from the Gewald three-component reaction between cyclohexanones, alkyl cyanoacet
