• One-pot synthesis of substituted indolo[1,2-a]quinolines under transition-metal-free conditions
  作者：Adisak Thanetchaiyakup、Hassayaporn Rattanarat、Nutthawat Chuanopparat、Paiboon Ngernmeesri

  A simple and efficient one-pot synthesis of substituted indolo[1,2-a]quinolines under transition-metal-free conditions has been developed. When 2-fluorobenzaldehyde was treated with substituted 2-methylindoles in the presence of Cs2CO3, the desired products were typically obtained in good to excellent yields. This reaction sequence involves a nucleophilic aromatic substitution and a Knoevenagel condensation

  2'-Substituted analogs of triclosan have been synthesized to target inhibition of the key malarial enzyme Plasmodium falciparum enoyl acyl carrier protein reductase (PfENR). Many of these compounds exhibit good potency (EC50<500 nM) against in vitro cultures of drug-resistant and drug-sensitive strains of the P. falciparum parasite and modest (IC50=1-20 microM) potency against purified PfENR enzyme

  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。
