  The Antibiotic CJ-15,801 Is an Antimetabolite that Hijacks and Then Inhibits CoA Biosynthesis

  摘要：

  The natural product CJ-15,801 is an inhibitor of Staphylococcus aureus, but not other bacteria. Its close structural resemblance to pantothenic acid, the vitamin precursor of coenzyme A (CoA), and its Michael acceptor moiety suggest that it irreversibly inhibits an enzyme involved in CoA biosynthesis or utilization. However, its mode of action and the basis for its specificity have not been elucidated to date. We demonstrate that CJ-15,801 is transformed by the uniquely selective S. aureus pantothenate kinase, the first CoA biosynthetic enzyme, into a substrate for the next enzyme, phosphopantothenoylcysteine synthetase, which is inhibited through formation of a tight-binding structural mimic of its native reaction intermediate. These findings reveal CJ-15,801 as a vitamin biosynthetic pathway antimetabolite with a mechanism similar to that of the sulfonamide antibiotics and highlight CoA biosynthesis as a viable antimicrobial drug target.

  Fast and Flexible Synthesis of Pantothenic Acid and CJ-15,801

  摘要：

  The fast and efficient syntheses of pantothenic acid and the antiparasitic agent CJ-15,801 have been achieved starting from a common imide unit through the selective manipulation of enamide intermediates.

  and the trans-substituted double bond of CJ-15,801 is important for the selective, on-target antiplasmodial effect, while replacement of the carboxyl group is permitted, and, in one case, favored. Additionally, we show that the antiplasmodial potency of CJ-15,801 analogues that retain the R-pantoyl and trans-substituted enamide moieties correlates with inhibition of P. falciparum pantothenate kinase

  人类疟疾寄生虫恶性疟原虫的存活取决于泛酸（维生素B 5），泛酸是基本酶辅因子辅酶A的前体。CJ-15,801，泛酸的酰胺类似物，从真菌Seimatosporium sp。分离。先前显示，CL28611可通过靶向泛酸利用来抑制恶性疟原虫的体外增殖。为了告知下一代类似物的设计，我们着手合成和测试了一系列合成的带有酰胺基的泛酸类似物。我们证明了R-泛酰基部分和反式的守恒CJ-15,801的双取代双键对于选择性的靶向抗血浆药物作用很重要，同时允许羧基取代，在一种情况下，这是有利的。此外，我们显示保留R-泛酰基和反式取代的酰胺基部分的CJ-15,801类似物的抗血浆活性与抑制恶性疟原虫泛酸激酶（Pf PanK）催化的泛酸磷酸化相关，暗示与Pf PanK的相互作用为抗疟原虫活性的关键决定因素。
