A compound represented by the formula (1) wherein ring A is a ring optionally having 1 to 3 substituents; ring B is a 1,2-azole ring which may further have 1 to 3 substituents; Xa, Xb and Xc are the same or different and each is a bond, - O -, - S - and the like; Ya is a divalent aliphatic hydrocarbon residue having 1 to 20 carbon atoms; Yb and Yc are the same or different and each is a bond or a divalent aliphatic hydrocarbon residue having 1 to 20 carbon atoms; ring C is a monocyclic aromatic ring which may further have 1 to 3 substituents; and R represents -OR4 (R4 is hydrogen atom or optionally substituted hydrocarbon group) and the like, or a salt thereof or a prodrug thereof is useful as an agent for the prophylaxis or treatment of diabetes and the like.
A series of new benzoxazepine derivatives substituted with different alkoxy and aryloxy group were synthesized comprising synthetic steps of Mitsunobu reaction, lithiumaluminumhydride (LAH) reduction, followed by debenzylation and finally intramolecular Mitsunobu cyclization. The new benzoxazepines specifically inhibited growth of breast cancer cell lines, MCF-7 and MDA-MB-231, but lack cytotoxicity
合成了一系列新的被不同烷氧基和芳氧基取代的苯并氮杂品衍生物,包括Mitsunobu反应的合成步骤,氢化铝锂(LAH)的还原步骤,随后的脱苄基作用以及最后的分子内Mitsunobu环化反应。新的苯并a氮平能特异性抑制乳腺癌细胞MCF-7和MDA-MB-231的生长,但对正常的HEK-293细胞没有细胞毒性。活性化合物诱导的细胞生长抑制是由于细胞周期停滞在G 0 / G 1期。该活性化合物可导致裸鼠模型MCF-7异种移植瘤的肿瘤体积明显减少,其活性与柠檬酸他莫昔芬在16 mg kg -1时的活性相当。治疗30天的剂量。与他莫昔芬相比,已确定的该系列最有效的化合物作为乳腺癌的抗癌剂具有特定优势。
Modified Borohydride Agents, 1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane Tetrahydroborate (BAAOTB) versus Tetrabutylammonium Tetrahydroborate (TBATB). Efficient, Selective, and Versatile Reducing Agents

日期:1995.9
1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane tetrahydroborate (BAAOTB) and tetrabutylammonium tetrahydroborate (TBATB) are used for the selective reductions of aldehydes, ketones, α,β-unsaturated carbonyl compounds, acid chlorides, azides, epoxides, and disulfides in t-BuOH and hexane/chloroform. ABBOAB with its rigid and bulky structure reacts more selectively than its analogue TBATB.

A diverse group of novel medium ring heterocycles derived from naturally abundant proteinogenic amino acids were evaluated for their potency towards antithrombotic activity. The more potent benzofused oxazepine and oxazocine scaffolds were diversified by incorporating different amino acids at the position number 3. Further the effect of ring size has also been taken into account and it was observed that the eight-membered oxazocines ane more potent compared to the corresponding oxazepines.
