  Optimization of troglitazone derivatives as potent anti-proliferative agents: Towards more active and less toxic compounds

  摘要：

  Δ2-Troglitazone derivatives were shown to exhibit anti-proliferative activity in a PPARγ-independent manner. We prepared various compounds in order to increase their potency and decrease their toxicity towards non-malignant primary cultured hepatocytes. Many compounds induced viabilities less than 20% at 10 μM on various cancer cell lines. Furthermore, five of them showed hepatocyte viability of 80% or more at 200 μM. In addition, compounds 17 and 18 exhibited promising maximum tolerated doses on a murine model, enabling future investigations.

  Design and synthesis of novel neuroprotective 1,2-dithiolane/chroman hybrids

  摘要：

  Novel 1,2-dithiolane/chroman hybrids bearing heterocyclic rings such as 1,2,4- and 1,3,4-oxadiazole, 1,2,3-triazole and tetrazole were designed and synthesized. The neuroprotective activity of the new analogues was tested against oxidative stress-induced cell death of glutamate-challenged HT22 hippocampal neurons. Our results show that bioisosteric replacement of amide group in 2-position of the chroman moiety, by 1,3,4- oxadiazole did not affect activity. However, analogue 5 bearing the 1,2,4- oxadiazole moiety showed improved neuroprotective activity. The presence of nitrogen heterocycles strongly influences the neuroprotective activity of 5-substituted chroman derivatives, depending on the nature of heterocycle. Replacement of the amide group of the first generation analogues by 1,2,4- oxadiazole or 1,2,3-triazole resulted in significant improvement of the activity against glutamate induced oxidative stress.

• Synthesis of α-Tocopherol Analogues
  作者：Cacang Suarna、Roger T. Dean、Peter T. Southwell-Keely

  DOI：10.1071/c97044

  日期：——

  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.
