  • Patent number: 10772837
    Abstract: The present invention provides modified release pharmaceutical compositions, and methods for administering the compositions to a user, including humans. The composition may contain a combination of ingredients in proportions calculated to achieve therapeutic effect, including at least the following ingredients: one or more natural or synthetic cannabinoids, one or more release modifying agent(s), and one or more pharmaceutically acceptable excipient(s). The composition may be in a multi-layered solid dosage form to provide fast, controlled and also sustained release of specific ingredients. More specifically, the invention relates to modified release pharmaceutical compositions comprising cannabinoids and a process for preparation thereof. More specifically, the invention may control drug release in accordance with the therapeutic purpose and pharmacological properties of active substances.

  • Patent number: 7344851
    Abstract: Prenylating enzymes are involved in modifying oncoproteins, such as RAS, so that growth of neoplastic cells becomes uncontrolled. Inactivation of such enzymes can prevent uncontrolled growth. ?-Dicarbonyl compounds can be used to covalently modify and thereby inactivate prenylating enzymes such as protein farnesyltransferase and protein geranylgeranyltransferase. The compounds can be designed to enhance affinity and/or specificity for a particular protein substrate.

  • Publication number: 20060111329
    Abstract: Oncoproteins such as Ras and RhoB are known to induce cell division in an unrestrained manner when such proteins are localized at the inner surface of a cancer cell membrane. The localization is effected by the prenylation reaction, whereby a hydrophobic group (e.g. a farnesyl group) is attached to the protein in the presence of an enzyme (e.g. farnesyl protein transferase). Deactivation of the prenylation enzyme through covalent modification can therefore ultimately result in the mitigation and/or cessation of cancer cell growth. Various prenylation inhibitors having the necessary structural groups to bond covalently, or essentially irreversibly, to the prenylation enzyme include carbonyl or thiocarbonyl compounds (or masked versions of these compounds) and alpha oxo-epoxides bonded to a hydrophobic, substrate-mimicking group. The carbonyl or thiocarbonyl compounds also contain a nucleofugal atom or group to enhance the tendency to form covalent bonds.
