抗疟候选药物 MMV008138 ( 1a ) 特别令人感兴趣,因为它的靶酶 (IspD) 在人类中不存在。为了获得更高的效力,并探测空间需求,制备了一系列1a类似物,其特征是 B 环和 C 环的甲基取代以及环链转换。X射线晶体学、核磁共振光谱和计算被用来研究这些修饰对C环构象和D环取向的影响。不幸的是,所有探索的 B 环和 C 环类似物都失去了体外抗疟活性。讨论了空间效应和构象变化对目标参与的可能作用。

for steric demand, a series of analogs of 1a were prepared that featured methyl-substitution of the B- and C-rings, as well as ring-chain transformations. X-ray crystallography, NMR spectroscopy and calculation were used to study the effects of these modifications on the conformation of the C-ring and orientation of the D-ring. Unfortunately, all the B- and C-ringanalogs explored lost in vitro antimalarial

A short and efficient synthesis of α-CH2-X functionalized tryptophan methyl ester (methyl 2-amino-3-(1H-indol-3-yl)propionate) is described, by alkylation of methyl 2-isocyano-3-(1H-indol-3-yl)propionate with a range of functionalized alkyl halides.
