the structures of CYP121 substrates. The resulting inhibitors have low micromolar affinity, good predicted physicochemical properties and selectivity for CYP121 over other Mtb P450s. Spectroscopic characterisation of the inhibitors' binding mode provides insight into the effect of weak nitrogen-donor ligands on the P450 heme, an improved understanding of factors governing CYP121-ligand recognition and
必需的结核分枝杆菌(Mtb)酶CYP121的环二肽底物被解构成其组成片段并针对该酶进行筛选。鉴定了许多命中,其中之一表现出意想不到的抑制剂样结合模式。阐明了抑制药效基团,并通过以CYP121底物的结构为指导的合成加工,迅速提高了片段结合亲和力。所得抑制剂与其他Mtb P450相比,具有较低的微摩尔亲和力,良好的预测理化性质和对CYP121的选择性。抑制剂结合模式的光谱表征可深入了解弱氮供体配体对P450血红素的影响,
