  摘要：

  制备的片段和合成前体与大环3-酰基四酸（= 3-酰基-1,5-二氢-4-羟基-2H-吡咯-2-酮）烟酰胺内酰胺和大环蛋白A以及其他类似物在环杂原子（N，O，S）中的残基（N，O，S）和N（1），C（3）和C（5）处的残基进行了细胞毒性和抗菌作用测试。在体外针对各种肿瘤细胞系的抗癌活性不一定需要完整的吡咯烷-2,4-二酮环。环丁草内酰胺的无环β-羟基-八碳三烯酰基酰胺前体也表现出独特的活性，IC 50（120 h）值<2.5μM。3-寡烯酰基残基的长度对抗癌活性几乎没有影响，但是3-碱-寡烯酰基四酸比其3-（4-甲氧基肉桂酰基）同类物更有效。NH-3-酰基丁二酸通常比其N-Me或N-Boc类似物更具活性，除非另外的极性基团需要增加亲脂性以充分摄取。与同等取代的四酸相比，Tetronic和thiotetronic酸在癌细胞中的抗增殖能力要低得多。

  Transformation of μ-opioid receptor agonists into biologically potent μ-opioid receptor antagonists

  摘要：

  N-Allylation (-CH2-CH=CH2) of [Dmt(1)]endomorphins yielded the following: (i) [N-allyl-Dmt(1)]endomorphin-2 (Dmt = 2',6'-dimethyl-L-tyrosine) (12) and [N-allyl-Dmt(1)]endomorphin-1 (15) (K-i mu = 0.45 and 0.26 nM, respectively) became p-antagonists (pA(2) = 8.59 and 8.18, respectively) with weak delta-antagonism (pA(2) = 6.32 and 7.32, respectively); (ii) intracerebroventricularly administered 12 inhibited morphine-induced CNS-mediated antinociception in mice [AD(50) (0.148 ng/mouse) was 16-fold more potent than naloxone], but not spinal antinociception, and (iii) 15 reversed the alcohol-elevated frequency in spontaneous inhibitory post-synaptic currents (IPSC) in hippocampal CA1 pyramidal cells in rat brain slices (P = 0.0055). Similarly, N-allylation of the potent mu-opioidmimetic agonists, 1,6-bis-[H-Dmt-NH]-hexane and 3,6-bis-[Dmt-NH-propyl]-2(1H)-pyrazinone, converted them into p-antagonists (pA(2) = 7.23 and 7.17 for the N-allyl-derivatives 17 and 19, respectively), and exhibited weak delta-antagonism. Thus, N-allylation of Dmt containing opioid peptides or opioidmimetics; continues to provide a facile means to convert selective mu-opioid agonists into potent mu-opioid antagonists.

  Thirty diketopiperazines were synthesized as analogs of cyclo (-Tyr-Arg-). The analgesic activities of these analogs were evaluated after intracerebral administration in mice. In the cyclo (-X-Arg-) series of analogs, cyclo [-Tyr (Et)-Arg-] showed the most potent activity. In the cyclo (-Tyr-Y-) series of analogs, the activity decreased in the order Y=homoarginine, p-guanidinophenylalanine, 2-amino-4-guanidinobutyric acid, Lys, Orn, His, α, γ-diaminobutyric acid and Pro. Among the analogs synthesized, cyclo-[-Tyr (Et)-Har-], which was designed on the basis of the above results, exhibited remarkably potent analgesic activity, being 17 times more potent than cyclo (-Tyr-Arg-) and nearly as potent as morphine on a molar basis. The structure-activity relation of cyclo(-Tyr-Arg-) is discussed in the light of these results.

  合成了30种双吡咯并哌嗪类环(-Tyr-Arg-)类似物，并评价了它们对小鼠脑室内给药后的镇痛活性。在环(-X-Arg-)系列类似物中，环[-Tyr(Et)-Arg-]显示出最强的活性。在环(-Tyr-Y-)系列类似物中，活性按Y=高精氨酸、对胍苯丙氨酸、2-氨基-4-胍基丁酸、赖氨酸、鸟氨酸、组氨酸、α,γ-二氨基丁酸和脯氨酸的顺序递减。在合成的类似物中，环-[-Tyr(Et)-Har-]基于上述结果设计，表现出极其强大的镇痛活性，比环(-Tyr-Arg-)强17倍，按摩尔计算几乎与吗啡一样有效。根据这些结果，讨论了环(-Tyr-Arg-)的构效关系。
