The present invention relates to compounds capable of acting as androgen receptor, antagonists, pharmaceutical formulations containing the same, and methods of use thereof. Such uses include, but are not limited to, use as antitumor agents, particularly for the treatment of cancers such as colon, skin and prostate cancer and to induce androgen receptor antagonist activity in a subject afflicted with an androgen-related affliction. Examples of androgen-related afflictions include, but are not limited to, baldness, hirsutism, behavioral disorders, acne, and uninhibited spermatogenesis wherein inhibition of spermatogenesis is so desired.

The invention encompasses constrained bicyclic and tricyclic CGRP-receptor antagonists, methods for identifying them, pharmaceutical compositions comprising them, and methods for their use in therapy for treatment of migraine and other headaches, neurogenic vasodilation, neurogenic inflammation, thermal injury, circulatory shock, flushing associated with menopause, airway inflammatory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), and other conditions the treatment of which can be effected by the antagonism of CGRP-receptors.

This invention relates to novel compounds which are thyroid receptor ligands, preferably antagonists, and to methods for using such compounds in the treatment of cardiac arrhythmias, thyrotoxicosis and subclinical hyperthyrodism.

The invention encompasses constrained bicyclic and tricyclic CGRP-receptor antagonists, methods for identifying them, pharmaceutical compositions comprising them, and methods for their use in therapy for treatment of migraine and other headaches, neurogenic vasodilation, neurogenic inflammation, thermal injury, circulatory shock, flushing associated with menopause, airway inflammatory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), and other conditions the treatment of which can be effected by the antagonism of CGRP-receptors

The present invention is directed to a new class of 6-sulfonamido-quinolin-2-one and 6-sulfonamido-2-oxo-chromene derivatives to their use as androgen antagonists, and to relieve conditions associated with inappropriate activation of the androgen receptor.

The invention relates to the field of medicine primers, and particularly discloses an application of IMB-A6 serving as an androgen receptor antagonist and an application of the IMB-A6 to preparation of androgen imbalance disease treating medicines and male contraception pills. By building a reliable androgen activity screening method, the inhibiting effect of a plurality of medicine primers on androgen receptor activity is tested to finally find that the IMB-A6 is a novel androgen receptor antagonist, and activity of wild and mutagenic androgen receptors can be inhibited. Further, activity of the prostate cancer resistance of the IMB-A6 is tested to find that the IMB-A6 has good activity for AR positive prostate cancer cells such as LNCaP and has no activity for AR negative prostate cancer cells, the expression activity of the androgen receptors can be inhibited, and the IMB-A6 is similar to positive medicines such as enzalutamide.

The invention provides tanshinone compounds, a preparation method and use thereof, and relates to the technical field of pharmaceutical chemistry. The tanshinone compounds possess a structure formula I or II as shown in the specification. The use of the tanshinone compounds includes but not limited to anticancer drugs, particularly the treatment of prostate cancer and bladder cancer, and induction of androgen receptor antagonist activity when patients have androgen-related diseases, wherein the androgen-related diseases include but not limited to multi-disease, acne, and spermatogenesis without inhibition in need of suppressing spermatogenesis.

The present invention is directed to a new class of 6-sulfonamido-quinolin-2-one and 6-sulfonamido-2-oxo-chromene derivatives to their use as androgen antagonists, and to relieve conditions associated with inappropriate activation of the androgen receptor.

Castrate resistant prostate cancer cell lines exhibiting resistance to the androgen-receptor antagonist enzaluatamide overexpress one or both of IGFBP-2 or IGFBP-5 when compared to non-resistant cell lines. Oligonucleotides that target IGFBP-2 and IGFBP-5 can be used to overcome this resistance or as part of a treatment program when administered concurrently with the administration of androgen-receptor antagonist treatments.

The present invention relates to an insulin-like growth factor (IGF) receptor antagonist for use in the treatment of prostate neoplasia, including benign prostatic hyperplasia (BPH), prostate cancer, and particularly CRPC, wherein the antagonist is used in combination with an androgen receptor antagonist. An embodiment of the invention is where the androgen receptor antagonist is enzalutamide.

Described herein are methods and compositions for the treatment of prostate cancer in a subject in need thereof. The prostate cancer may be a castration resistant and an androgen receptor antagonist-resistant prostate cancer. The methods may comprise administering to the subject a CYP17-lyase inhibitor of Formula II.

The present invention relates to novel substituted thioimidazolidinone compounds and pharmaceutical compositions comprising such compounds for treatment of androgen receptor-associated diseases or disorders, such as prostate cancer, benign prostatic hypertrophy, male hair loss, muscle loss, acne and hirsutism.

Disclosed are compounds, compositions and methods for treating and / or ameliorating diseases, syndromes, disorders, or conditions associated with AR mutant receptors linked to castration-resistant prostate cancer, in a subject, including a mammal and / or human, in need thereof, who has demonstrated resistance to a first or second generation AR antagonist, comprising, consisting of, and / or consisting essentially of, administering to a subject in need thereof, a therapeutically effective amount of a compound of Formula (I)wherein R1, G, R10, and R11 are defined herein.
