  Discovery, Synthesis, and Biological Evaluation of Thiazoloquin(az)olin(on)es as Potent CD38 Inhibitors

  摘要：

  A series of thiazoloquin(az)olinones were synthesized and found to have potent inhibitory activity against CD38. Several of these compounds were also shown to have good pharmacokinetic properties and demonstrated the ability to elevate NAD levels in plasma, liver, and muscle tissue. In particular, compound 78c was given to diet induced obese (DIO) C57Bl6 mice, elevating NAD > 5-fold in liver and >1.2-fold in muscle versus control animals at a 2 h time point. The compounds described herein possess the most potent CD38 inhibitory activity of any small molecules described in the literature to date. The inhibitors should allow for a more detailed assessment of how NAD elevation via CD38 inhibition affects physiology in NAD deficient states.

  A new series of 6-substituted quinolin-2-one thiosemicarbazides 6a–j has been synthesized. The structure of the target compounds was proved by different spectroscopic and elemental analyses. All the designed final compounds were evaluated for their in vitro activity against the urease-producing R. mucilaginosa and Proteus mirabilis bacteria as fungal and bacterial pathogens, respectively. Moreover, all compounds were in vitro tested as potential urease inhibitors using the cup-plate diffusion method. Compounds 6a and 6b were the most active with (IC50 = 0.58 ± 0.15 and 0.43 ± 0.09 µM), respectively, in comparison with lead compound I (IC50 = 1.13 ± 0.00 µM). Also, the designed compounds were docked into urease proteins (ID: 3LA4 and ID: 4UBP) using Open Eye® software to understand correctly about ligand–receptor interactions. The docking results revealed that the designed compounds can interact with the active site of the enzyme through multiple strong hydrogen bonds. Moreover, rapid overlay of chemical structures’ analysis was described to understand the 3D QSAR of synthesized compounds as urease inhibitors. The results emphasize the importance of polar thiosemicarbazide directly linked to 6-substituted quinolone moieties as promising antimicrobial urease inhibitors.

  一系列6-取代的喹啉-2-酮硫脲6a–j已被合成。目标化合物的结构通过不同的光谱和元素分析得到证实。所有设计的最终化合物分别对产生脲酶的R. muciLAginoSA和Proteus mirabilis细菌作为真菌和细菌病原体的体外活性进行了评估。此外，所有化合物在体外采用杯盘扩散法作为潜在的脲酶抑制剂进行了测试。化合物6a和6b活性最强，分别为（IC50 = 0.58 ± 0.15和0.43 ± 0.09μM），与先导化合物I（IC50 = 1.13 ± 0.00μM）相比。此外，设计的化合物通过Open Eye®软件对接入脲酶蛋白（ID：3LA4和ID：4UBP），以正确理解配体-受体相互作用。对接结果显示，设计的化合物可以通过多个强氢键与酶的活性位点相互作用。此外，还描述了化学结构的快速叠加分析，以理解合成的化合物作为脲酶抑制剂的3D QSAR。结果强调了直接连接到6-取代喹诺酮部分的极性硫脲作为有前途的抗菌脲酶抑制剂的重要性。
