Despite the success of imatinib in CML therapy through Bcr-Abl inhibition, acquired drug resistance occurs over time in patients. In particular, the resistance caused by T315I mutation remains a challenge in clinic. Herein, we embarked on a structural optimization campaign aiming at discovery of novel Bcr-Abl inhibitors toward T315I mutant based on previously reported dibenzoylpiperazin derivatives. We proposed that incorporation of flexible linker could achieve potent inhibition of Bcr-AblT315I by avoiding steric clash with bulky sidechain of Ile315. A library of 28 compounds with amino acids as linker has been developed and evaluated. Among them, compound AA2 displayed the most potent activity against Bcr-AblWT and Bcr-AblT315I, as well as toward Bcr-Abl driven K562 and K562R cells. Further investigations indicated that AA2 could induce apoptosis of K562 cells and down regulate phosphorylation of Bcr-Abl. In summary, the compounds with amino acid as novel flexible linker exhibited certain antitumor activities, providing valuable hints for the discovery of novel Bcr-Abl inhibitors to overcome T315I mutant resistance, and AA2 could be considered as a candidate for further optimization.

Sulfonyl derivatives represented by general formula (I), salts of the same, and solvates of both: and application of them as drugs: [wherein R1is hydrogen, hydroxyl, nitro or the like; R2and R3are each independently hydrogen, halogeno or the like; R4and R5are each dependently hydrogen, halogeno or the like; Q1is an optionally substituted saturated or unsaturated 5- or 6-membered cyclic hydrocarbon group or the like; Q2is a single bond, oxygen or the like; Q3is, e.g., a group represented by formula (a): T1is carbonyl or the like; and X1and X2are each independently methylidyne or nitrogen]. These compounds exhibit potent Fxa inhibiting activities and serve as excellent anticoagulants which speedily exert satisfactory and persistent anti-thrombotic effects through oral administration and little cause adverse effects.

Sulfonyl derivatives represented by the following general formula (I): Q1-Q2-T1-Q3-SO2-QA and drugs containing the same (wherein Q1 is an optionally substituted, saturated or unsaturated, five- or six-membered cyclic hydrocarbon group, a five- or six-membered heterocyclic group, or the like; Q2 is a single band, oxygen, sulfur, C1-C6 alkylene or the like; QA is optionally substituted arylalkenyl, heteroarylalkenyl or the like; and T1 is carbonyl or the like). These compounds have potent FXa-inhibitory effects and promptly exert satisfactory and persistent antithrombotic effects through oral administration, thus being useful as anticoagulant agents little accompanied with side effects.
