A polystyrene-supported Pd complex bearing a cyclic pyridine-2,6-bisiamide ligand was synthesized and its catalytic activity in the Suzuki–Miyaura coupling reaction of 2,6-bromopyridine with 4-methoxyphenylboronic acid in aqueous media was investigated. The solid-supported catalyst exhibited catalytic activity and chemoselectivity that were comparable to those of homogeneous catalyst. The reusability of the solid-supported catalyst was also examined.

A series of novel pyridine-bridged analogues of combretastatin-A4 (CA-4) were designed and synthesized. As expected, the 4-atom linker configuration retained little cytotoxicities in the compounds 2e, 3e, 3g, and 4i. Activities of the analogues with 3-atom linker varied widely depending on the phenyl ring substitutions, and the 3-atom linker containing nitrogen represents the more favorable linker structure. Among them, three analogues (4h, 4s, and 4t) potently inhibited cell survival and growth, arrested cell cycle, and blocked angiogenesis and vasculature formation in vivo in ways comparable to CA-4. The superposition of 4h and 4s in the colchicine-binding pocket of tubulin shows the binding posture of CA-4, 4h, and 4s are similar, as confirmed by the competitive binding assay where the ability of the ligands to replace tubulin-bound colchicine was measured. The binding data are consistent with the observed biological activities in antiproliferation and suppression of angiogenesis but are not predictive of their antitubulin polymerization activities.
