Current therapeutic approaches to osteoporosis display some potential adverse effects and a limited efficacy on non-vertebral fracture reduction. Some sulfonylamidines targeting the scaffold proteins prohibitins-1 and 2 (PHB1/2) have been showed to inhibit the formation of osteoclasts in charge of bone resorption. Herein, we report the development of a second generation of anti-osteoclastic PHB ligands. The most potent compound, IN45, showed 88% inhibition at the low concentration of 5 μM, indicates that it might serve as a basis for the development of new antiosteoporotic drugs.

A Co-catalyzed coupling of 3-(2-isocyanoethyl)indoles with organic azides in pure water for accessing spiroindolenine derivatives was developed. This strategy features mild reaction conditions, high atom-economy, excellent yields, wide substrate scopes, and broad functional group tolerance. The products were obtained simply by sequential operation involving extraction, concentration, precipitation, and filtration, without tedious column chromatography. More importantly, the aqueous catalytic system could be recycled at least ten times without reducing the catalytic activity. The strategy provides a green and efficient method for the construction of spiroindolenine derivatives.

A one-pot procedure for the synthesis of novel 1,2,3-triazole derivatives (5a–5l) in good yields (63 to 77%) using different sulfonic acids and 4-(prop-2-yn-1-yl)thiomorpholine 1,1-dioxide through the in situ generated sulfonyl azides was developed. The structures of the newly synthesized compounds were confirmed by 1H NMR, 13C NMR, mass spectrometry, and elemental analysis. The newly synthesized compounds were screened for in?vitro antibacterial activity and free radical scavenging activity in terms of hydrogen donating or radical scavenging ability by the DPPH method. Among all, the compound N-(4-((4-((1,1-dioxidothiomorpholino) methyl)-1H-1,2,3-triazol-1-yl)sulfonyl)phenyl) acetamide (5l) was found to exhibit potent activity as compared to the standard drugs.
