  Studies on hindered phenols and analogs. 1. Hypolipidemic and hypoglycemic agents with ability to inhibit lipid peroxidation

  摘要：

  A series of hindered phenols were investigated as hypolipidemic and/or hypoglycemic agents with ability to inhibit lipid peroxidation. 1,3-Benzoxathioles (9 and 22), phenoxypentanoic acid (34), phenoxypentanol (35a), phenoxynonanol (35b), phenylchloropropionic acid having a chromanyl group (25), and a thiazolidine compound (27) derived from 25, all having a hindered phenol group, were prepared and examined. Compound 27 showed the expected biological properties in vivo and in vitro without any liver weight increase. Biological activities of the analogous thiazolidine compounds, 43-58, were compared. Thus, (+/-)-5-[4-[(6-hydroxy-2,5,7,8-tetramethylchroman-2-yl)methoxy]- benzyl]-2,4-thiazolidinedione (27) (CS-045) was found to have all of our expected properties and was selected as a candidate for further development as a hypoglycemic and hypolipidemic agent.

• Synthesis and Antioxidant Activity Evaluation of Trolox Derivatives

  To find potent antioxidants, 16 novel Trolox derivatives were designed and synthesized via a reduction and esterification reaction. The chemical structures were characterized by NMR and MS. Trolox derivatives were employed to explore the potential structure–antioxidant activity relationships using three different assays. The results revealed that some of the synthesized compounds exhibited stronger antioxidant activities than L-ascorbic acid and Trolox, which suggests such compounds warrant further study.

  为了寻找高效的抗氧化剂，设计并通过还原和酯化反应合成了16种新颖的Trolox衍生物。这些化合物的化学结构通过NMR和MS进行了表征。采用三种不同的检测方法探讨了Trolox衍生物的结构与抗氧化活性之间的关系。研究结果表明，部分合成的化合物展现出比L-抗坏血酸和Trolox更强的抗氧化活性，提示这些化合物值得进一步研究。

  The subject invention provides pharmaceutical compounds useful in the treatment of Type II diabetes. These compounds are advantageous because they are readily metabolized by the metabolic drug detoxification systems. Particularly, thiazolidinedione analogs that have been designed to include esters within the structure of the compounds are provided. This invention is also drawn to methods of treating disorders, such as diabetes, comprising the administration of therapeutically effective compositions comprising compounds that have been designed to be metabolized by serum or intracellular hydrolases and esterases. Pharmaceutical compositions of the ester-containing thiazolidinedione analogs are also taught.

  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.
