标 题:Modulation of solubility, stability, absorption, metabolism, and pharmacokinetic profile of lipophilic drugs by sterols
发明人：DHINGRA OM
权利人:MARIUS PHARMACEUTICALS INC
摘要:A formulation for drug delivery, providing enhanced modulation of solubility, stability, absorption, metabolism, and/or pharmacokinetic profile of a lipophilic therapeutic agent by formulation with sterols and/or sterol esters, resulting in higher bioavailability of a therapeutic agent administered to a subject in need of such therapeutic agent. The formulation contains a therapeutic agent and a sterol or sterol ester, and can, optionally, further contain a solubilizer and/or an enhancing agent. Also described are pharmaceutical compositions containing the formulations and methods of making and methods of using the formulations and pharmaceutical compositions. Formulations of the disclosure can be constituted to minimize the synthesis of dihydrotestosterone when the therapeutic agent includes testosterone or testosterone esters.

标题 :Methods for preparing synthetic bile acids and compositions comprising the same
发明人：MORIARTY ROBERT M; RAO PHOTON
权利人:MORIARTY ROBERT M; RAO PHOTON; KYTHERA BIOPHARMACEUTICALS INC
摘要:This invention relates generally to methods for preparing certain bile acids from non-mammalian sourced starting materials as well as to synthetic bile acids and compositions comprising such acids wherein the acids are characterized by a different C 14 population than naturally occurring bile acids as well as being free from any mammalian pathogens. This invention is also directed to the synthesis of intermediates useful in the synthesis of such bile acids. Accordingly, the C ring of the steroidal scaffold is oxidized to provide a synthetic route and intermediates to DCA. This invention also provides synthetic methods for preparing deoxycholic acid or a salt thereof starting from aromatic steroids such as estrogen, equilenin, and derivatives thereof. This invention is also directed to intermediates such as 12-oxo or delta-9,11-ene steroids as well as novel processes for their preparation. In preferred embodiments, bile acids are provided herein which have substituents on the B-ring and/or D-ring side chain and optionally on the hydroxy group of the A-ring.

摘要:A composition is provided, wherein the composition comprises a water-swellable, water insoluble polymer, a blend of a hydrophilic polymer and a complementary oligomer capable of hydrogen bonding to the hydrophilic polymer, and a whitening agent, preferably a peroxide. The composition finds utility as a tooth whitening composition and is applied to the teeth in need of whitening, and then removed when the degree of whitening has been achieved. In certain embodiments, the composition is translucent. Methods for preparing and using the compositions are also disclosed.
