Department of Medicinal Chemistry, SmithKline Beecham Pharmaceuticals, Essex, UK. Tetrahedron: Asymmetry (1999), 10(7), 1335-1351. Publisher: Elsevier Science Ltd., CODEN: TASYE3 ISSN: 0957-4166. Journal written in English. CAN 131:144536 AN 1999:369513 CAPLUS (Copyright (C) 2009 ACS on SciFinder (R)) Abstract The synthesis of a new series of potent 2-oxy-3-arylpropanoic acid antihyperglycemic agents in both racemic and non-racemic form is described. (the biol. activity of these compds. was not reported here). Resoln. of racemic acids is accomplished via amide formation with either (S)-2-phenylglycinol or (S)-4-benzyl-2-oxazolidinone as complementary resolving agents. The target compds. were ?-alkoxy-4-[2-[(2-benzoxazolyl)amino]ethoxy]benzenepropanoic acid derivs.

CAN 125:238227 AN 1996:573179 CAPLUS (Copyright (C) 2009 ACS on SciFinder (R)) Abstract The thiazolidine-2,4-dione ring of insulin-sensitizing antidiabetic agents can be replaced by ?-acyl-, ?-alkyl- and ?-(aralkyl)-carboxylic acids. The inclusion of an addnl. lipophilic moiety affords compds., equipotent to BRL 48482.

A review with 22 refs. The 5-benzylthiazolidine-2,4-dione moiety of insulin sensitizing antidiabetic agents can be replaced by a range of ?-heteroatom functionalized ?-phenylpropanoic acids. ?-Oxy-carboxylic acids show potent antidiabetic activity and one compd., the ?-ethoxyacid (SB 213068), is one of the most potent antihyperglycemic agents yet reported.
