  Synthesis and Evaluation of a Series of 3,4,5-Trimethoxycinnamic Acid Derivatives as Potential Antinarcotic Agents

  摘要：

  A series of 3,4,5‐trimethoxycinnamic acid derivatives was prepared and evaluated for antinarcotic effects on morphine dependence in mice and binding affinities on serotonergic receptors. The key synthetic strategies involve generation of ketones 6–7, esters 9–12 through condensation reaction, and amides 13–19 via coupling reaction using 1‐hydroxybenzotriazole/ethyl(dimethylaminopropryl)carbodiimide system in high yield. We found that the naloxone‐induced morphine withdrawal syndrome was significantly suppressed by new synthetic 3,4,5‐trimethoxycinnamic acid derivatives (20 mg/kg/day). Most of 3,4,5‐trimethoxycinnamic acid derivatives were found to have high affinity to 5‐HT1A receptor. The naloxone‐induced morphine withdrawal syndrome was attenuated by (+)8‐OH‐DPAT (0.1 mg/kg/day, i.p.), a 5‐HT1A receptor agonist. In cortical neuronal cells, (+)8‐OH‐DPAT (1 μm) produced an elevation of the pERK 1/2 expression, and the elevated pERK levels were inhibited by WAY 100635, a 5‐HT1A receptor‐specific antagonist. Interestingly, the pERK levels were increased by the 3,4,5‐trimethoxycinnamic acid derivatives and the derivatives‐mediated changes in pERK levels were blocked by the WAY 100635. These results suggested that new synthetic 3,4,5‐trimethoxycinnamic acid derivatives have a potential antinarcotic effect through acting as a 5‐HT1A receptor agonist in mice.

  Recently, the diarylpentanoid BP-M345 (5) has been identified as a potent in vitro growth inhibitor of cancer cells, with a GI50 value between 0.17 and 0.45 µM, showing low toxicity in non-tumor cells. BP-M345 (5) promotes mitotic arrest by interfering with mitotic spindle assembly, leading to apoptotic cell death. Following on from our previous work, we designed and synthesized a library of BP-M345 (5) analogs and evaluated the cell growth inhibitory activity of three human cancer cell lines within this library in order to perform structure–activity relationship (SAR) studies and to obtain compounds with improved antimitotic effects. Four compounds (7, 9, 13, and 16) were active, and the growth inhibition effects of compounds 7, 13, and 16 were associated with a pronounced arrest in mitosis. These compounds exhibited a similar or even higher mitotic index than BP-M345 (5), with compound 13 displaying the highest antimitotic activity, associated with the interference with mitotic spindle dynamics, inducing spindle collapse and, consequently, prolonged mitotic arrest, culminating in massive cancer cell death by apoptosis.

  最近，人们发现二芳基戊烷类化合物 BP-M345 (5) 是一种有效的体外癌细胞生长抑制剂，其 GI50 值介于 0.17 至 0.45 µM 之间，对非肿瘤细胞的毒性较低。BP-M345 (5) 通过干扰有丝分裂纺锤体的组装，促进有丝分裂停滞，导致细胞凋亡。在之前工作的基础上，我们设计并合成了一个 BP-M345 (5) 类似物文库，并评估了该文库中三种人类癌细胞株的细胞生长抑制活性，以便进行结构-活性关系（SAR）研究，并获得具有更好抗沉降作用的化合物。有四个化合物（7、9、13 和 16）具有活性，其中化合物 7、13 和 16 的生长抑制作用与明显的有丝分裂停止有关。这些化合物的有丝分裂指数与 BP-M345 (5)相似，甚至更高，其中化合物 13 的抗有丝分裂活性最高，它干扰了有丝分裂纺锤体的动力学，导致纺锤体崩溃，从而延长了有丝分裂停滞时间，最终导致大量癌细胞凋亡。
