ef-24 ef-24 ef-24 is a compound that is a synthetic analogue of curcumin, a bioactive phytochemical from turmeric. curcumin has antioxidant, antibiotic, anti-inflammatory and anti-cancer properties in vitro but has low potency and very poor bioavailability when taken orally, resulting in limited efficacy. ef-24 was developed to try to improve upon these properties, and has been found to be around 10x more potent than curcumin and with much higher systemic bioavailability. it has never been developed for medical use, though research continues to investigate whether it may be useful as an adjuvant treatment for some cancers alongside conventional chemotherapy drugs. ef-24identifiers iupac name (3e,5e)-3,5-bispiperidin-4-one cas number342808-40-6pubchem cid9885748chemspider8061422uniio5yt36mst0chemblchembl379849chemical and physical dataformulac19h15f2nomolar mass311.332 g·mol−13d model (jsmol)interactive image smiles c\1nc/c(=c\c2=cc=cc=c2f)/c(=o)/c1=c/c3=cc=cc=c3f inchi inchi=1s/c19h15f2no/c20-17-7-3-1-5-13(17)9-15-11-22-12-16(19(15)23)10-14-6-2-4-8-18(14)21/h1-10,22h,11-12h2/b15-9+,16-10+key:nivyqysnruifif-kavgswpwsa-n
