GKK1032B is a fungal metabolite that has antiproliferative and antibacterial activities. GKK1032B inhibits the growth of HeLa S3 cervical and MCF-7 breast cancer cells and Vero cells. It also inhibits the growth of B. subtilis and M. tuberculosis.

GKK1032B is an alkaloid compound that can be found in endophytic fungus Penicillium sp. GKK1032B can induce the apoptosis of human osteosarcoma MG63 cells through caspase pathway activation[1].

Among them, GKK1032B showed significant cytotoxicity against human osteosarcoma cell line MG63 with an IC50 value of 3.49 μmol·L-1, and a primary mechanistic study revealed that it induced the apoptosis of MG63 cellsvia caspase pathway activation._x000D_ _x000D_ Reference: Chin J Nat Med. 2022 Jan;20(1):67-73. https://pubmed.ncbi.nlm.nih.gov/35101251/
