  Anibamine, a novel pyridine quaternary alkaloid isolated from Aniba sp., was found to effectively compete with 125I-gp120 in binding to the chemokine receptor CCR5, with an IC50 = 1 μM. Anibamine is the first natural product reported as a CCR5 antagonist, and thus provides a novel structural skeleton unique from other lead compounds that have generally been identified from high-throughput screening efforts

  最近的研究表明，CCR5趋化因子受体可能是治疗前列腺癌的潜在靶标。因此，CCR5拮抗剂的开发可以提供新颖的前列腺癌治疗方法。发现Anibamine是一种从Aniba sp。分离的新型吡啶季生物碱，其与趋化因子受体CCR5的结合可有效与125 I-gp120竞争，其IC 50为50 = 1μM。茴香胺是第一个被报道为CCR5拮抗剂的天然产物，因此提供了一种不同于其他先导化合物的新颖结构骨架，而这些先导化合物通常是从高通量筛选工作中鉴定出来的。为了改善先导化合物的结构并提高阿尼巴胺衍生物作为潜在的抗前列腺癌药物的治疗指数，在这项工作的结构-活性关系研究中采用了“解构-重建-精制”的方法。在这里，我们报告阿尼巴明和17类似物的设计，合成和抗前列腺癌活性。从结果在体外和体内在此描述的研究表明，这类化合物有潜力提供新颖的引线作为抗前列腺癌试剂。

  Iodo- or 2-bromopyridine N-oxides were readily magnesiated with i-PrMgCl·LiCl via the iodine or bromine−magnesium exchange. The bromine adjacent to pyridine N-oxide (at the 2- or 6-position) can be regioselectively magnesiated in the presence of other position substituted halogens. This method was tested in various substituted pyridine N-oxide systems, and has been successfully applied to the total

  碘或2-溴吡啶N-氧化物很容易通过碘或溴-镁交换与i- PrMgCl·LiCl镁化。可以在其他位置取代的卤素存在下，将与吡啶N-氧化物相邻的溴（在2-或6-位）进行区域选择性氧化。该方法已在各种取代的吡啶N-氧化物系统中进行了测试，已成功地应用于铜霉素E和A的全合成。

  The synthesis of 3-pyridinols carrying alkyltelluro, alkylseleno, and alkylthio groups is described together with a detailed kinetic, thermodynamic, and mechanistic Study of their antioxidant activity. When assayed for their capacity to inhibit azo-initiated peroxidation of linoleic acid in a water/chlorobenzene two-phase system, tellurium-containing 3-pyridinols were readily regenerable by N-acetylcysteine contained in the aqueous phase. The best inhibitors quenched peroxyl radicals more efficiently than alpha-tocopherol, and the duration of inhibition was limited only by the availability of the thiol reducing agent. fn homogeneous phase, inhibition of styrene autoxidation absolute rate constants k(inh) for quenching of peroxyl radical were as large as 1 x 10(7) M-1 s(-1), thus Outperforming the best phenolic antioxidants including alpha-tocopherol. Tellurium-containing 3-pyridinols could be quantitatively regenerated in homogeneous phase by N-tert-butoxycarbonyl cysteine methyl ester, a lipid-soluble analogue of N-acetylcysteine. In the presence of an excess of the thiol, a catalytic mode of action was observed, similar to the one in the two-phase system. Overall, compounds bearing the alkyltelluro moiety ortho to the OH group were much more effective antioxidants than the corresponding para isomers. The origin of the high reactivity of these compounds was explored using pulse-radiolysis thermodynamic measurements, and a mechanism for their unusual antioxidant activity was proposed. The tellurium-containing 3-pyridinols were also found to catalyze reduction of hydrogen peroxide in the presence of thiol reducing agents, thereby acting as multifunctional (preventive and chain-breaking) catalytic antioxidants.
• The potential role of anibamine, a natural product CCR5 antagonist, and its analogues as leads toward development of anti-ovarian cancer agents

  Chemokines and their receptors play important roles in the development of primary tumors and their metastases. Particularly CC chemokine receptor 5 (CCR5) and its ligand CC chemokine ligand 5 (CCL5/RANTES) seem to be critical in proliferation and invasion of ovarian cancer, the leading cause of death from gynecological malignancies in the United States. Anibamine, the first natural product CCR5 antagonist, and its analogues were examined for their effects on proliferation of the OVCAR-3 ovarian cancer cells in order to validate their candidacy as leads to develop novel anti-ovarian cancer agents. Acting as CCR5 antagonists, anibamine and its analogues significantly suppressed CCL5-induced intracellular Ca2+ flux. The compounds also inhibited the proliferation of OVCAR-3 at micromolar to submicromolar range. Moreover, anibamine and several analogues did not show significant cytotoxicity in NIH 3T3 cells at concentrations up to 20 mu M. Based on these results, anibamine and one of its synthetic analogues were defined as potential leads to develop novel agents against ovarian cancer. Published by Elsevier Ltd.
