- Discovery and optimization of 7-aminofuro[2,3-c]pyridine inhibitors of TAK1
-
The discovery and potency optimization of a series of 7-aminofuro[2,3-c] pyridine inhibitors of TAK1 is described. Micromolar hits taken from high-throughput screening were optimized for biochemical and cellular mechanistic potency to ~10 nM, as exemplified by compound 12az. Application of structure-based drug design aided by co-crystal structures of TAK1 with inhibitors significantly shortened the number of iterations required for the optimization.

- Synthesis of highly substituted cyclobutane fused-ring systems from n-vinyl β-lactams through a one-pot domino process
-
In this contribution, aminocyclobutanes, as well as eight-membered enamide rings, have been made from N-vinyl β-lactams. The eightmembered products have been formed by a [3,3]-sigmatropic rearrangement, whereas the aminocyclobutanes have been derived from a domino [3,3]-rearrangement/6π- electrocyclisation process. The aminocyclobutanes have been obtained in a highly diastereoselective fashion. The cyclobutane ring system tolerates fusion even if adjacent quaternary centres are present. Systems containing up to four fused rings are readily accessible. The reaction profile has been investigated by using Gaussian 03. This study suggests that two reaction pathways for aminocyclobutane formation are possible. In one pathway the [3,3]-sigmatropic rearrangement is the rate-limiting step and in the second pathway the electrocyclisation is rate limiting. Taken together, these reactions should facilitate the construction of fused heterocycles.

- Design and synthesis of piperazinylpyridine derivatives as novel 5-HT 1A agonists/5-HT3 antagonists for the treatment of irritable bowel syndrome (IBS)
-
We have prepared a series of piperazinylpyridine derivatives for the treatment of irritable bowel syndrome (IBS). These compounds, which were designed by pharmacophore analysis, bind to both serotonin subtype 1A (5-HT 1A) and subtype 3 (5-HT3) receptors. The nitrogen atom of the isoquinoline, a methoxy group and piper-azine were essential to the pharmacophore for binding to these receptors. We also synthesized furo- and thienopyridine derivatives according to structure-activity relationship analyses. Compound 17c (TZB-20810) had high affinities to these receptors and exhibited 5-HT1A agonistic activity and 5-HT3 antagonistic activity concurrently, and is a promising drug for further development in the treatment of IBS.

- Furopyridines. I. Synthesis of Furopyridine
-
The parent framework of furopyridine has been synthesized. 3-Furoic acid chloride (2) was reduced with bis(triphenylphosphine) copper(I) tetrahydroborate to afford 3-furaldehyde (3) which was condensed with malonic acid to give β-(3-furyl)acrylic acid (4).The acrylic acid 4 was converted to the acid azide (5), which in turn was cyclized to give furopyridin-7(6H)-one (6) by heating at 180 deg in diphenylmethane.The pyridone 6 was chlorinated with phosphorus oxychloride, followed by reduction with zinc and acetic acid to give furopyridine (8).
