prepared and evaluated as inhibitors of human leukocyte elastase (HLE). In addition, a new series of acyl, urea, and carbamate derivatives of 7-amino-4-chloro-3-methoxyisocoumarin (1), 7-amino-4-chloro-3-propoxyisocoumarin (3), and 7-amino-4-chloro-3-(2-bromoethoxy)isocoumarin (6) have been synthesized. Most of the synthesized compounds are very potent inhibitors of HLE with kobs/[I] values between 10(4)
已经制备了具有各种3-烷氧基取代基的一系列3-烷氧基-7-氨基-4-氯异香豆素,并将其评估为人白细胞弹性蛋白酶(HLE)的抑制剂。此外,还推出了一系列新的7-氨基-4-氯-3-甲氧基异香豆素(1),7-氨基-4-氯-3-丙氧基异香豆素(3)和7-氨基-香豆素的酰基,脲和氨基甲酸酯衍生物已经合成了4-氯-3-(2-溴乙氧基)异香豆素(6)。大多数合成的化合物都是非常有效的HLE抑制剂,其kobs / [I]值在10(4)和10(6)M-1 s-1之间。异香豆素环7-氨基位置的疏水取代基为HLE提供了最佳的选择性和抑制能力。在2-溴乙氧基系列中,具有PhNHCONH 7取代基的化合物24的kobs / [I]值为1.2 x 10(6)M-1 s-1,对HLE具有很高的选择性,并且是最有效的HLE抑制剂。经过HLE测试。在长链L-苯丙氨酰基衍生物中,kobs / [I]值为1.8 x 10(5)M-1

Protein CK2 has gained much interest as an anticancer drug target in the past decade. We had previously described the identification of a new allosteric site on the catalytic α-subunit, along with first small molecule ligands based on the 4-(4-phenylthiazol-2-ylamino)benzoicacid scaffold. In the present work, structure optimizations guided by a binding model led to the identification of the lead compound

Carbon‐13 NMR spectra are reported for 69 substituted methyl benzoates in deuteriochloroform or in its mixture with dimethylsulphoxide‐d6. The substituent‐induced chemicalshifts (SCS) of the CO carbon correlate poorly with dual substituent parameters (DSP) in all possible modifications, and for meta derivatives in particular this correlation is both overpara meterized and imprecise. A much better
The object of the present invention is to provide a novel method for producing an isothiocyanate compound having a carboxyl group(s) by a reaction of the corresponding amino compound having a carboxyl group(s), thiocarbonyldiimidazole and a base, in one step with high purity.
An amino compound having a carboxyl group(s) is reacted with thiocarbonyldiimidazole in a solvent in the presence of a base to obtain an isothiocyanate compound having a carboxyl group(s).
