Inhibitory and Cooperative Effects Regulated by pH in Host-Guest Complexation between Cationic Pillar[5]arene and Reactive 2-Carboxyphthalanilic Acid

The study of host-guest complexation between reactive 2-carboxyphthalanilic acid (CPA) and two cationic pillararenes has been carried out. Host-guest complexation with significant kinetic effects was observed only with the smaller cavity size pillararene (P5A). Kinetics in the pH range 1.50-6.40, ESI-MS, 1H NMR titration, and ROESY experiments were performed to characterize the complexes. High binding stoichiometry (H:G2) was observed for all CPA protonation states. The system is pH-dependent, and inversion of cooperativity (negative to positive) occurs by increasing the dianionic CPA2- concentration (allosteric behavior). Toward physiological pH, association constant K1:1 does not change (104 M-1), and K1:2 increased from 102 to 104 M-1, as well as the inhibitory effect increased up to 222-fold. NMR results elucidated the structure of the complex and allowed us to create a map of H-H interactions that describes well the diversity and number of interactions in the complex. ?

Design, synthesis and anticancer activities evaluation of novel 5H-dibenzo[b,e]azepine-6,11-dione derivatives containing 1,3,4-oxadiazole units

Rucaparib and PJ34 were used as the structural model for the design of novel 5H-dibenzo[b,e]azepine-6,11-dione derivatives containing 1,3,4-oxadiazole units. And target compounds were successfully synthesized through a 3-step synthetic strategy. All target compounds were screened for their anti-proliferative effects against OVCAR-3 cell line. Preliminary biological study of these compounds provided potent compounds d21 and d22 with better activities than Rucaparib.
