Nimbin
Nimbolide is a triterpene compound that can be isolated from neem (Azadirachta indica), possesses anticancer and antiproliferative activity. Nimbolide induces tumor cell apoptosis by inhibiting NF-κB and CDK4/CDK6 kinase. Nimbolide suppresses the Wnt, PI3K-Akt, MAPK and JAK-STAT signaling pathways[1][2].
