  摘要：

  芳基亚胺由于其可回收性和易于合成而在动态共价材料中提供了前景。然而，它们的光触发E / Z异构现象却很少受到关注。这是由于其亚稳态（<60 id=25>Z 异构体）的低热稳定性、表现出出色的抗疲劳性以及在室温下的热半衰期长达 19.2 小时等挑战造成的。此外，它们还表现出 T可见光照射下的光致变色特性、定量组装和可接近性使这些光开关有别于其基于偶氮的类似物，这些发现为下一代光响应动态共价材料开辟了道路。通过这些新的光致变色联系和光控动态组合化学的进一步探索。

  of hexafluoroisopropyl carbamate-based irreversible inhibitors of MGLL, culminating in a highly potent, selective, and orally available, CNS-penetrant MGLL inhibitor, 28 (ABX-1431). Activity-based protein profiling experiments verify the exquisite selectivity of 28 for MGLL versus other members of the serine hydrolase class. In vivo, 28 inhibits MGLL activity in rodent brain (ED50 = 0.5-1.4 mg/kg)

  丝氨酸水解酶单酰基甘油脂酶（MGLL）将内源性大麻素受体激动剂2-花生四烯酰基甘油（2-AG）和其他单酰基甘油转化为脂肪酸和甘油。MGLL的遗传或药理失活导致中枢神经系统2-AG升高，花生四烯酸和类二十烷酸相应减少，从而产生抗伤害性，抗焦虑和抗神经炎作用，而没有引起直接大麻素受体激动剂的全部精神活性作用。在这里，我们报告了基于六氟异丙基氨基甲酸酯的MGLL不可逆抑制剂的优化，最终形成了一种高效，选择性和口服的CNS渗透性MGLL抑制剂28（ABX-1431）。基于活性的蛋白质谱分析实验证明了MGLL与丝氨酸水解酶类别的其他成员相比具有28的出色选择性。在体内，28在鼠福尔马林疼痛模型中抑制了啮齿动物大脑中的MGLL活性（ED50 = 0.5-1.4 mg / kg），增加了大脑2-AG的浓度，并抑制了疼痛行为。ABX-1431（28）目前正在人类临床试验中进行评估。

  strategy, we broke this consensus and discovered a catalyst-free photodecarbonylation of the aldehyde group. It revealed that decarbonylation can be easily achieved with visible light irradiation by introducing a tertiary amine into the ortho-position of the aldehyde group. A diverse array of tertiary amines is tolerated by our photodecarbonylation under mild conditions. Furthermore, the (QM) computations

  几乎共识是，醛基（–CHO）的脱羰不仅需要通过过渡金属催化剂来介导，而且还需要严格的反应条件（高温和长反应时间）。在这项工作中，受“基于构象选择性的”设计策略的启发，我们打破了这一共识，并发现了醛基的无催化剂光脱羰基。它表明，脱羰基化可以用可见光照射能够容易地实现通过引入叔胺到邻醛基的-位置。在温和条件下，我们的光脱羰基化可以耐受各种各样的叔胺。此外，在精心设计的特殊底物上进行机理和实验的（QM）计算表明，我们的光脱羰基取决于醛基和叔胺的构象特异性，并通过异常的[1,4] -H位移和随后的[1,3] -H移位。
