The present invention relates to novel compounds of Formula I and their use in therapeutic treatments. The invention further relates to a novel chiral synthesis of 5,6,7,(8-substituted)-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazines using N-sp3 protective groups. The invention also provides intermediates for use in the synthesis of compounds of Formula I. ##STR00001##

The present invention provides bivalent inhibitors of BET bromodomains, such as compounds of Formulae (I), (II), (III), (IV), (V) and (VI). Some bromdomain-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 refers to a new enzymatic process for obtaining 17-monoesters of cortexolone and/or its 9,11-dehydroderivatives starting from the corresponding 17,21-diesters which comprises an enzymatic alcoholysis reaction. Furthermore, the present invention refers to new crystalline forms of cortexolone-17-propionate and 9,11-dehydro-cortexolone 17-butanoate.

Described herein is a method for forming multi-layer drug dosage forms having at least two layers. In the method, a first formulation comprising a non-gelling matrix forming agent and having a first density is dosed into a preformed mold. A second formulation comprising a non-gelling matrix former and having a second density not equal to the first density is subsequently dosed into the preformed mold. Then, the combination of the formulations dosed into the mold is freeze dried to form the multi-layer dosage form having at least two layers. The use of a density difference between the first and second formulations ensures formation of a product with two distinct layers.

The present invention provides 3-[2-fluoro-5-(2,3-difluoro-6-methoxybenzyl-oxy)-4-methoxyphenyl]-2,4-dioxo-1,2,3,4-tetrahydrothieno[3,4-d]pyrimidine-5-carboxylic acid choline salt having excellent solubility and storage stability.
