摘要： A method of cancer intervention or eradication by administering an effective amount of an endogenous ligand for the aryl hydrocarbon (Ah) receptor (AhR) named ITE or one of its analogs (the active ingredient) to a subject with cancer is disclosed. An effective dose and dosing frequency of the active ingredient are determined by measuring its blood levels of the subject after dosing. The active ingredient formulated with a carrier system is applied topically, enterally, or parenterally to the subject. The formulated drug can also be administered together with one or more of other cancer therapeutic agents. A maintenance dosing is provided after the subject is free of cancer to insure the cancer eradication. Subjects with cancers of prostate, liver, lung, ovarian, and breast are preferably accepted for treatment.

摘要： Disclosed is an aryl hydrocarbon receptor modulator of formula (I), and a pharmaceutically acceptable salt thereof, wherein R′ is H, CN, CH2(OH)R0, CmH2m+1, CnH2n−1, CnH2n−3, two Ra are independently H or two Ra together form =0 or ═N—W3—R1; A is a C6 to C10 aromatic ring unsubstituted or substituted with 1 to 3 R, or a C2-C10 heteroaromatic ring interrupted by 1 to 5 heteroatoms selected from N, 0, and S or a 4 to 7 membered nonaromatic heterocyclic ring containing C═N and interrupted by 1 to 3 heteroatoms selected from N, 0, and S, with either one unsubstituted or substituted with 1 to 3 R; Q is R, or is a C6 to C10 aromatic ring or a C2 to C10 heteroaromatic ring unsubstituted or substituted with 1 to 3 R and interrupted by 1 to 5 heteroatoms selected from N, 0, and S; and R is RC which is C-attached or RN which is N-attached. The compounds of formula (I) of the present invention can regulate AhR activity, and can be used to inhibit the growth of cancer cells and inhibit the metastasis and invasion of tumor cells.
