Inhibition of concise enzymes in ergosterol biosynthesis is one of the most prominent strategies for antifungal chemotherapy. Nevertheless, the enzymes sterol C5-desaturase and sterol C22-desaturase, which introduce double bonds into the sterol core and side chain, have not been fully investigated yet for their potential as antifungal drug targets. Lathosterol side chain amides bearing N-alkyl groups...
Increasing resistance of clinically relevant fungi is causing major problems in anti-mycotic therapy. Particularly for immunosuppressed patients fungal infections are of concern and increasing resistance against clinically used antimycotic drugs is hampering successful treatment. In the search for new antifungals ergosterol biosynthesis still is the most prominent target. However, several pitfalls...
Inhibition of cholesterol biosynthesis offers the opportunity for treatment of cardiovascular diseases. Numerous enzymes are involved in the post-squalene part of this biosynthesis, and selective inhibitors for almost all of the enzymes involved there have been described in literature. The only exception is the enzyme lathosterol oxidase (EC 1.14.21.6), for which up to now no selective inhibitor has...
A whole-cell assay for screening cholesterol biosynthesis inhibitors in the post-squalene pathway has been developed. HL 60 cells were incubated for 24h with test substances. The nonsaponifiable lipids were extracted by means of liquid–liquid extraction using tert-butylmethylether. The raw extracts were purified by dispersive solid phase extraction using a primary–secondary amine material (PSA) and...
