  Novel Antidiabetic and Hypolipidemic Agents. 5. Hydroxyl versus Benzyloxy Containing Chroman Derivatives

  摘要：

  Several thiazolidinediones having chroman moieties were synthesized and evaluated for their euglycemic and hypolipidemic activities. Some of the analogues having an aminoalkyl group as a linker between the chroman ring and 4-[5-(2,4-dioxo-1,3-thiazolidinyl)methyl]phenoxy moiety seem to be better than troglitazone. In vitro transactivation assays of PPAR gamma have been carried out with these glitazones to understand their molecular mechanism. For the first time we have found that some of the unsaturated thiazolidinediones are superior to their saturated counterpart in the in vivo assay. A more potent thiazolidinedione analogue than troglitazone is reported. Pharmacokinetic studies have shown that protection of the OH group in the chroman moiety leads to a decrease in metabolism, thereby resulting in a superior pharmacological profile.

  日期：2006.12

  The synthesis of tocopherol fatty alcohols (TFAs), potent microglial activation modulators, was achieved via C-alkylation of trimethylhydroquinone. Several analogs, in particular water-soluble prodrugs, have been synthesized using a Wittig reaction and their antioxidant activities have been evaluated.

  A range of a-tocopherol analogues of varying side-chain length and structure has been prepared by the Wittig reaction of alkyltriphenylphosphonium bromides with either 6-benzyloxy-2,5,7,8-tetramethylchroman- 2-carbaldehyde (8) or 6-acetoxy-2,5,7,8-tetramethylchroman-2-carbaldehyde (14). These analogues include 2-hexyl-2,5,7,8-tetramethylchroman-6-ol (11), 2-heptyl-2,5,7,8-tetramethylchroman-6-ol (12) and 2,5,7,8-tetramethyl-2-(pent-1-enyl)chroman-6-ol (15). Methoxycarbonylmethyl 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylate (2) was formed by reaction of the triethylammonium salt of trolox (1) with methyl bromoacetate. Reaction of methoxycarbonylmethyltriphenylphosphonium bromide (16) with (8) did not produce the expected methyl 3-(6-benzyloxy-2,5,7,8-tetramethylchroman-2-yl)prop-2-enoate (17), but rather 4-(6-benzyloxy-2,5,7,8-tetramethylchroman-2-yl)but-3-en-2-one (22). A proposed mechanism for this unusual reaction is discussed.

  Conjugates of lupane triterpenoids (betulin and betulonic and betulinic acids) with synthetic analogs of α-tocopherol were obtained via ester bond formation and tested in vitro. Showing low cytotoxicity, some of them suppress nitrogen monoxide production without affecting the activity of arginase, which suggests their antiinflammatory and immunomodulating properties.

  Novel antioxidants, derivatives of trolox, and selected phenolic acids have been prepared in good yields and fully characterized by 1H NMR, 13C NMR, and MS. Their antioxidant activities have been assessed by DPPH and ORAC assays, and during frying and accelerated storage tests. Novel phenolic compounds exhibited higher radical scavenging activities than both trolox and α-tocopherol. Trolox hydroxybenzoate
