Lavendustin B is a weak tyrosine kinase inhibitor that has been used as a negative control for lavendustin A. Lavendustin A strongly inhibits epidermal growth factor receptor-associated tyrosine kinase, competes with ATP, and is noncompetitive with the peptide. Lavendustin B was previously identified as an inhibitor of HIV-1 integrase (IN) interaction with its cognate cellular cofactor, lens epithelium-derived growth factor (LEDGF/p75).
