Several alkynes and azides were prepared starting from betulinic acid and Baylis-Hillman reaction-derived allylic alcohols. These alkynes and azides were then coupled under click cycloaddition conditions to obtain functionalized betulinic acid-triazole conjugates. Similarly, pyrazinyl- and indolylbetulinic acid-triazoles were also prepared employing cycloaddition chemistry. All the synthetic compounds were tested for their cytotoxicity against murine breast cancer (4T1) and human pancreatic cancer (MIA PaCa-2) cell lines. Based on these in vitro assays, two series of compounds have been identified as lead compounds for further development.

Botrytis blight is a very destructive disease caused by Botrytis spp., infecting flowers, trees, vegetables and fruits. Twelve new compounds were prepared by the reaction of potassium N-aryl-sulfonyldithiocarbimates with Morita-Baylis-Hillman derivatives

The treatment of ischemic stroke (IS) remains a big challenge in clinics, and it is urgently needed to develop novel, safe, and effective medicines against IS. Here, we report the design, synthesis, and biological evaluation of organic NO2- donors as potential agents for the treatment of IS. The representative compound 4a was able to slowly generate low concentrations of NO2- by reaction with a thiol-containing nucleophile, and the NO2- was selectively converted into NO under ischemic/hypoxia conditions to protect primary rat neurons from oxygen-glucose deprivation and recovery (OGD/R)-induced cytotoxicity by enhancing the Nrf2 signaling and activating the NO/cGMP/PKG pathway. Treatment with 4a at 2 h before or after ischemia mitigated the ischemia/reperfusion-induced brain injury in middle cerebral artery occlusion (MCAO) rats by producing NO and enhancing Nrf2 signaling. Furthermore, 4a significantly promoted endothelial cell proliferation and angiogenesis within the ischemic penumbra. Our findings suggest that this type of NO2- donors, like 4a, may be valuable to fight IS and other ischemic diseases.
