  Derivatives of Natural Product Agrimophol as Disruptors of Intrabacterial pH Homeostasis in Mycobacterium tuberculosis

  摘要：

  This article reports the rational medicinal chemistry of a natural product, agrimophol (1), as a new disruptor of intrabacterial pH (pH(IB)) homeostasis in Mycobacterium tuberculosis (Mtb). Through the systematic investigation of the structure-activity relationship of 1, scaffold-hopping of the diphenylmethane scaffold, pharmacophore displacement strategies, and studies of the structure-metabolism relationship, a new derivative 5a was achieved. Compound 5a showed 100-fold increased potency in the ability to reduce pH(IB) to pH 6.0 and similarly improved mycobactericidal activity compared with 1 against both Mycobacterium bovis-BCG and Mtb. Compound 5a possessed improved metabolic stability in human liver microsomes and hepatocytes, lower cytotoxicity, higher selectivity index, and similar pK(a) value to natural 1. This study introduces a novel scaffold to an old drug, resulting in improved mycobactericidal activity through decreasing pH(IB), and may contribute to the critical search for new agents to overcome drug resistance and persistence in the treatment of tuberculosis.

  It is urgent to introduce new drugs for tuberculosis to shorten the prolonged course of treatment and control drug-resistant Mycobacterium tuberculosis (Mtb). One strategy toward this goal is to develop antibiotics that eradicate both replicating (R) and nonreplicating (NR) Mtb. Naturally occurring (+)-calanolide A was active against R-Mtb. The present report details the design, synthesis, antimycobacterial activities, and structure-activity relationships of synthetic calanolides. We identified potent dual-active nitro-containing calanolides with minimal in vitro toxicity that were cidal to axenic Mtb and Mtb in human macrophages, while sparing Gram-positive and -negative bacteria and yeast. Two of the nitrobenzofuran-containing lead compounds were found to be genotoxic to mammalian cells. Although genotoxicity precluded clinical progression, the profound, selective mycobactericidal activity of these calanolides will be useful in identifying pathways for killing both R- and NR-Mtb, as well as in further structure-based design of more effective and drug-like antimycobacterial agents.
