  Synthesis of Gallinamide A Analogues as Potent Falcipain Inhibitors and Antimalarials

  摘要：

  Analogues of the natural product gallinamide A were prepared to elucidate novel inhibitors of the falcipain cysteine proteases. Analogues exhibited potent inhibition of falcipain-2 (FP-2) and falcipain-3 (FP-3) and of the development of Plasmodium falciparum in vitro. Several compounds were equipotent to chloroquine as inhibitors of the 3D7 strain of P. falciparum and maintained potent activity against the chloroquine-resistant Dd2 parasite. These compounds serve as promising leads for the development of novel antimalarial agents.

  Gallinamide A的总合成，立体化学赋形和抗疟活性

  摘要：

  描述了没食子酰胺A（蓝细菌来源的抗疟疾十肽）的总合成和立体化学分配。胆碱酰胺A的四种可能的N端非对映异构体（包括天然产物symplostatin 4）的合成是通过从共同的酰亚胺片段中分离出来的策略实现的。天然产物和相应的非对映异构体以最长的线性步骤（共8步）合成，总收率为30-33％。四种合成的非对映异构体与分离的天然产物的比较NMR光谱研究表明，没食子酰胺A具有二甲基化的LN末端的异亮氨酰残基。因此，我们证明了没食子酰胺A在结构和立体化学上均与Symplostatin 4相同。还显示出没食子酰胺A及其N端非对映异构体对恶性疟原虫的3D7菌株具有显着的抗疟活性，其IC 50值在纳摩尔范围内。

  reisolated and characterized as a potent, selective, and irreversible inhibitor of the human cysteine protease cathepsin L. Molecular docking identified potential modifications to improve binding, which were synthesized as a suite of analogs. Resultingly, this current study produced the most potent gallinamide analog yet tested against cathepsin L (10, Ki = 0.0937 ± 0.01 nM and kinact/Ki = 8 730 000). From a

  SARS-CoV-2. The marine natural product gallinamide A and several synthetic analogues were identified as potent inhibitors of cathepsin L with IC50 values in the picomolar range. Lead molecules possessed selectivity over other cathepsins and alternative host proteases involved in viral entry. Gallinamide A directly interacted with cathepsin L in cells and, together with two lead analogues, potently inhibited

  The marine natural product symplostatin 4 (Sym4) has been recognized as a potent antimalarial agent. However, its mode of action and, in particular, direct targets have to date remained elusive. We report a chemical synthesis of Sym4 and show that Sym4-treatment of P. falciparum-infected red blood cells (RBCs) results in the generation of a swollen food vacuole phenotype and a reduction of parasitemia at nanomolar concentrations. We furthermore demonstrate that Sym4 is a nanomolar inhibitor of the P. falciparum falcipains in infected RBCs, suggesting inhibition of the hemoglobin degradation pathway as Sym4's mode of action. Finally, we reveal a critical influence of the unusual methyl-methoxypyrrolinone (mmp) group of Sym4 for potent inhibition, indicating that Sym4 derivatives with such a mmp moiety might represent viable lead structures for the development of antimalarial falcipain inhibitors.
