A composition includes a contraceptive chimeric virus-like particle with an antigenic carrier domain and one or more antigenic regions from a sperm cell in the antigenic carrier domain, with the antigenic carrier domain including human papillomavirus L1 capsid protein and the antigenic regions including one or more structural elements of the Catsper ion channel complex. When administered to a patient, the contraceptive vaccine stimulates production of anti-sperm antibodies that, upon binding to a sperm cell, inhibit the sperm cell's motility and thus inhibit the ability of the sperm cell to fertilize an egg cell. The induced immunoinfertility of the composition can be reversed for brief or extended lengths of time by overdosing the patient with a reversal agent lacking the antigenic carrier domain but having a protein sequence substantially identical to that of the one or more antigenic regions to sequester the anti-sperm antibodies.

A drug delivery system for oral administration of hydrophobic drugs with enhanced and extended absorption and improved pharmacokinetics is provided. In one embodiment, formulations comprising testosterone and testosterone esters, e.g., testosterone palmitate, are disclosed. Methods of treating a hormone deficiency or effecting male contraception with the inventive formulations are also provided.

The present disclosure relates to inhibitors of mitochondrial function. Methods of screening compounds for mitochondrial inhibition are disclosed. Also described are methods of using mitochondrial inhibitors called mitoriboscins—mitochondrial-based therapeutic compounds having anti-cancer and antibiotic properties—to prevent or treat cancer, bacterial infections, and pathogenic yeast, as well as methods of using mitochondrial inhibitors to provide anti-aging benefits. Specific mitoriboscin compounds and groups of mitoriboscins are also disclosed.

The present invention provides bivalent inhibitors of BET bromodomains, such as compounds of Formulae (I), (II), (III), (IV), (V), and (VI). Some bromodomain-containing proteins (e.g., BRD4) have a tandem bromodomain primary structure comprising more than one bromodomain binding site (e.g., BRD4 comprises BD1 and BD2). Bivalent inhibitors of BET bromodomains provided herein can target bromodomains through advantageous multivalent interactions, and can therefore can be to treat diseases or conditions associated with bromodomain-containing proteins. The present also provides pharmaceutical compositions and kits comprising the inventive compounds, as well as methods of using the inventive compounds.

The present invention provides compounds and pharmaceutically compositions thereof. The compounds and compositions are binders of bromodomains and/or bromodomain-containing proteins (e.g., bromo and extra terminal (BET) proteins). Also provided are methods, uses, and kits using the compounds and pharmaceutical compositions for inhibiting the activity (e.g., increased activity) of bromodomains and/or bromodomain-containing proteins and for treating and/or preventing in a subject diseases associated with bromodomains or bromodomain-containing proteins (e.g., proliferative diseases, cardiovascular diseases, viral infections, fibrotic diseases, metabolic diseases, endocrine diseases, and radiation poisoning). The compounds, pharmaceutical compositions, and kits are also useful for male contraception.

The 6H-thieno[2,3-e][1,2,4]triazolo[3,4-c][1,2,4]triazepine derivatives or salts thereof of the present invention have BRD4 inhibitory activity, and thus, they are useful as medicaments, in particular, as prophylaxis and/or therapeutic agents for diseases associated with BRD4.

The present invention provides for compounds of formula (I)

##STR00001##

wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.6, X.sup.1, and X.sup.2 have any of the values defined in the specification, and pharmaceutically acceptable salts thereof, that are useful as agents in the treatment of diseases and conditions, including inflammatory diseases, cancer, and AIDS. Also provided are pharmaceutical compositions comprising compounds of formula (I).
