Bioisosteric replacement and scaffold hopping are powerful strategies in drug design useful for rationally modifying a hit compound towards novel lead therapeutic agents. Recently, we reported a series of thienopyrimidinones that compromise dynamics at the p66/p51 HIV-1 reverse transcriptase (RT)-associated Ribonuclease H (RNase H) dimer interface, thereby allosterically interrupting catalysis by altering the active site geometry. Although they exhibited good submicromolar activity, the isosteric replacement of the thiophene ring, a potential toxicophore, is warranted. Thus, in this article, the most active 2-(3,4-dihydroxyphenyl)-5,6-dimethylthieno[2,3-d]pyrimidin-4(3H)-one 1 was selected as the hit scaffold and several isosteric substitutions of the thiophene ring were performed. A novel series of highly active RNase H allosteric quinazolinone inhibitors was thus obtained. To determine their target selectivity, they were tested against RT-associated RNA-dependent DNA polymerase (RDDP) and integrase (IN). Interestingly, none of the compounds were particularly active on (RDDP) but many displayed micromolar to submicromolar activity against IN.

Several anthranilamide-based 2-phenylcyclopropane-1-carboxamides 13a-f, 1,1’-biphenyl-4-carboxamides 14a-f and 1,1’-biphenyl-2-carboxamides 17a-f were obtained by a multistep procedure starting from the (1S,2S)-2-phenylcyclopropane-1-carbonyl chloride 11, the 1,1'-biphenyl-4-carbonyl chloride 12 or the 1,1'-biphenyl-2-carbonyl chloride 16 with the appropriate anthranilamide derivative 10a-f. Derivatives 13a-f, 14a-f and 17a-f showed antiproliferative activity against human leukemia K562?cells. Among these derivatives 13b, 14b and 17b exerted a particular cytotoxic effect on tumor cells. Derivative 17b showed a better antitumoral effect on K562?cells than 13b and 14b. Analyses performed to explore 17b mode of action revealed that it induced an arrest in G2/M phase of cell cycle which was consequent to DNA lesions as demonstrated by the increase in phospho-ATM and γH2AX, two known markers of DNA repair response system. The effect of 17b was also related to ROS generation, activation of JNK and induction of caspase-3 dependent apoptosis.

Several new 2-(2-phenoxyacetamido)benzamides 17a-v, 21 and 22 were synthesized by stirring in pyridine the acid chlorides 16a-e and the appropriate5-R-4-R1-2-aminobenzamide 15a-e and initially evaluated in vitro for antiproliferative activity against the K562 (human chronic myelogenous leukemia) cell line. Some of synthesized compounds were evaluated for their in vitro antiproliferative activity against the full NCI tumor cell line panel derived from nine clinically isolated cancer types (leukemia, non-small cell lung, colon, CNS, melanoma, ovarian, renal, prostate and breast). The most active compounds caused an arrest of K562 cells in the G0-G1 phase of cell cycle and induction of apoptosis, which was mediated by caspase activation.

Design and synthesis of 6,7-dimethoxyquinazoline analogs as multi-targeted ligands for α1- and AII-receptors antagonism

Multiple-targeted ligands can have certain advantages for the management of hypertension which has multiple controls. Molecules with dual bioactivities are available in literature for treating metabolic disorders like diabetes, hypertension and hypercholesterolemia. After scrutinizing the SAR of prazosin-type α1-blockers and AII-antagonists it was planned to develop dual α1- and AII-antagonists. Five series of quinazoline derivatives were synthesized and evaluated as dual α1- and AII-antagonists on rat aortic strips for the blockade of known α1- and AII-agonist mediated contractions. Many compounds showed balanced activity on both the receptors but compound (22) was found to be the most active derivative having higher antagonistic activity on both the receptors. In the in vivo experiments the chosen compound (22) was slightly less active than prazosin but was found to be equipotent to losartan. These findings shed a new light on the structural requirements for both α1- as well as AII-receptor antagonists.
