1-[2,4-Dihydroxy-6-methoxy-3-(3-methyl-2-buten-1-yl)phenyl]-3-(4-hydroxyphenyl)-2-propen-1-one (Xanthohumol) , prenylchacone flavonoid, is a natural product with multi-biofunctions purified from Hops Humulus lupulus,is effective against HIV-1 and might serve as an interesting lead compound. It may represent a novel chemotherapeutic agent for HIV-1 infection.

6-Geranylnaringenin is a natural product from Humulus lupulus.

Xanthohumol and xanthohumol D are potent inducers of quinone reductase, suggests that they could be used as chemoprevention agents.

Xanthohumol, also known as 2', 4, 4'-trihydroxy-6'-methoxy-3'-prenylchalcone or desmethylxanthohumol, is a member of the class of compounds known as 3-prenylated chalcones. It inhibits COX-1 and COX-2 activity and shows chemopreventive effects.

Desmethylxanthohumol shows estrogenic activity.

5-O-Methylnaringenin is a marker, reduced MS detection of 5-O-methylnaringenin indicated that nifedipine may preferably remove a proton from the 5-position OH group in the A ring of the flavonoid skeleton.

α-Humulene (Alpha-caryophyllene) is extracted from S.officinalis essential oil.α-Humulene can inhibit tumor cell growth.α-Humulene also shows anti-inflammatory effects, probably by interfering with TNFalpha production and COX-2 and iNOS expression.

3'-Methylflavokawin shows cytotoxicity against HeLa cells, the IC 50 value comparable to xanthohumol (8.2-19.2 microM).

8-Prenylnaringenin is a phytoestrogen with high estrogenic activity,

(2S)-6-Prenylnaringenin (6-Prenylnaringenin) is an isomer of the potent phytoestrogen, 8-prenylnaringenin. (2S)-6-Prenylnaringenin is the most potent compound in the forebrain and acts as a positive allosteric modulator of GABAA at the α+β binding site.
