Background technology
The transformation and modification of natural steroid are increasingly paid close attention to by people, by some specific modifications, such as steroid
The modification of body ring, side chain, can obtain some important better than parent bioactive steroid derivatives【Levina,
I.S.;Pokrovskaya,E.V.;Kulikova,L.E.;Kamernitzky,A.V.;Kachala,V.V.;Smirnov,
A.N.Steroids.2008,73,815】.Such as have been used to the Abiraterone acetate ester (abiraterone of clinic
Acetate), chemical entitled 17- (3- pyridine radicals) androstane -5, -3 β of 16- diene-acetic acid esters are public by Centocor Ortho
The enzyme irreversible inhibitors of orally active CYP 17 of exploitation are taken charge of, by changing into abiraterone to testis and other body parts
Such as the androgen of adrenal gland generation plays inhibitory action.The approval listing of the Nikkei U.S. FDA of April 28 in 2011, is combined with metacortandracin
Treatment prostate cancer【G.A.Potter,S.E.Barrie,M.Jarman and M.G.Rowlands,J.Med.Chem.,
1995,38,2463.】.
Many researchs find, when steroidal D rings are modified, if it is possible to retain the carbonyl of steroidal C-17, and in the neighbour of carbonyl
Some characteristic side chains are introduced on position C-16, the physiological function better than parent compound is equally obtained in that

2004, Dubey et al. synthesized a series of 16- (styryl that 4- replaces)-androstane -5- ene derivatives by multistep, carefully
Cytoactive test shows that this is the new cytotoxic drug of a class, by three kinds of cancer cells to human body:Breast cancer cell
The anticancer experiment in vitro of MCF-7, lung carcinoma cell NCI-H460 and central nerve tumor cell SF-268 these three human cancer cells,
It was found that these compounds can induce the cancer cell-apoptosis of human body, so as to suppress the propagation of tumour cell【Dubey,S.;

An imidazole radicals is bonded on the basis of 17- carbonyl, biological activity test shows the work with very strong suppression cancer cell
With【Ranju,B.;Sheetal,G.;Sridhar,T.;Subhash,L.;Patwar,R.Steroids.2012,77,621.】.
Recently research finds such as there are multiple alkenyls in steroidal ring, can more strengthen the physiologically active of steroidal compounds.Such as
Gabriele M. in 2015Et al. three polyene-based steroids are separated to from sponge Callyspongia cf.C.flammea
Body compound, especially it is worth noting that there is C (8)=C that general steroid derivative is not commonly formed in these steroidal compounds
(14) alkenyl.There is these compounds suppression Aftin-5 cells to produce Ab-42 and be used to treat senile dementia.
