    1. Neutrophil growth factors (NGFs) stimulate neutrophil growth and survival. The first synthetic cytokinin-derived NGF was recently discovered and is a prospective drug owing to its potential use in anti-inflammatory therapy. The metabolism of some cytokinin-derived drugs (e.g. R-roscovitine, olomoucine II) has already been studied and it has been shown that they may give rise to drug-drug interactions. 2. In this in vitro study, the interactions of the novel neutrophil growth factor NGF1568 with two of the main classes of human drug-metabolizing enzymes, cytochromes P450 (CYPs) and UDP-glucuronosyltransferases (UGTs), were tested. Of the CYPs evaluated, NGF1568 was found to inhibit only CYP2C9, by an uncompetitive mechanism and with a K(i) value of 349 mu M.
