A multifunctional GO–IO–CS nanocomposite was synthesized. The nanocomposite can effectively capture and eliminate bacteria, and largely destroy bacteria biofilms under NIR irradiation.

A series of two classes of 3-phenylpyrazolopyrimidine-1,2,3-triazole conjugates were synthesized using click chemistry approach. All compounds were evaluated for inhibition of Src kinase and human ovarian adenocarcinoma (SK-Ov-3), breast carcinoma (MDA-MB-361), and colon adenocarcinoma (HT-29). Hexyl triazolyl-substituted 3-phenylpyrazolopyrimidine exhibited inhibition of Src kinase with an IC(50) value of 5.6 μM. 4-Methoxyphenyl triazolyl-substituted 3-phenylpyrazolopyrimidine inhibited the cell proliferation of HT-29 and SK-Ov-3 by 73% and 58%, respectively, at a concentration of 50 μM.

An improved, simple, and facile synthesis of amidoalkyl naphthols by employing three-component one-pot condensation reaction of β-naphthol, aromatic aldehydes, and amides in ionic liquids using ytterbium triflate as a mild Lewis acid catalyst is described. Advantageously, amidoalkyl naphthols were obtained in high yield under eco-friendly, economical, and non-corrosive conditions, and the catalyst was recycled.
