Betulonaldehyde is a pentacyclic triterpenoid and derivative of the cholesterol biosynthesis inhibitor betulin that has been found in Betula. It is active against P. falciparum (IC50 = 3.36 µg ml) and cytotoxic to NCI H187 lung cancer cells and non-cancerous Vero cells (IC50s = 19.23 and 17.09 µg ml, respectively). Topical application of betulonaldehyde (1 mg ear) reduces ear edema induced by phorbol 12-myristate 13-acetate (TPA; Item No. 10008014) in mice. It has also been used a precursor in the semisynthesis of C-2 and C-28 betulonic aldehyde derivatives.
Carbazomycin B is a bacterial metabolite that has been found in Streptomyces and has diverse biological activities. It is active against a panel of seven fungi and a panel of seven bacteria, as well as P. falciparum and C. albicans. It is also active against a panel of five plant pathogenic fungi. Carbazomycin B is cytotoxic to MCF-7, KB, NCI H187, and Vero cells. It also inhibits 5-lipoxygenase (5-LO) activity in RBL-1 cell extracts (IC50 = 1.5 µM).
