Paragraph 0090-0092; 0101-0102, (2021/06/21)
The invention belongs to the technical field of medicines, particularly relates to the field of treatment of tumor-related diseases, and relates to a biphenyl formamide urea compound, and a preparation method and application thereof. In order to solve the problem that the effect of a ROCK inhibitor in the prior art still needs to be improved, the invention provides the biphenyl formamide urea compound represented by formula (I) shown in the specification. The novel biphenyl formamide urea ROCKI inhibitor is prepared through a dominant fragment heterozygosis design strategy, so that the novel biphenyl formamide urea ROCKI inhibitor can simultaneously extend into target key binding regions (a pocket A and a pocket D) to improve the target affinity with the ROCKI inhibitor; further, the ROCK inhibition effect and the anti-tumor effect are improved.

The triazenyl-pyrimethamine derivative 3a (TAB), a potent and selective inhibitor of Pneumocystis carinii DHFR, was selected as the starting point for a lead optimization study. Molecular modeling studies, corroborated by a recent crystal structure determination of the ternary complex of P. carinii DHFR-NADPH bound to TAB, predicted that modifications to the acetoxy residue of the lead inhibitor could exploit binding opportunities in the vicinity of an active site pocket bounded by residues Ile33, Lys37, and Leu72. Substitutions in the benzyl moiety with electron-donating and electron-withdrawing groups were predicted to probe face-edge interactions with amino acid Phe69 unique to the P. carinii enzyme. New triazenes 10a-v and 12a-f were prepared by coupling the diazonium tetrafluoroborate salt 6b of aminopyrimethamine with substituted benzylamines or phenethylamines. The most potent of the new inhibitors against P. carinii DHFR was the naphthylmethyl-substituted triazene 10t (IC50: 0.053 μM), but a more substantial increase in potency against the rat liver DHFR led to a reduction in selectivity (ratio rat liver DHFR IC50/P. carinii DHFR IC50: 5.36) compared to the original lead structure 3a (ratio rat liver DHFR IC50/P. carinii DHFR IC50: 114).
