Pharmaceutical preparation of camptothecin-containing polymer derivative
Provided is a pharmaceutical preparation composition comprising a polymerized camptothecin derivative which is obtained by bonding a camptothecin derivative to a polymer carrier, and has nanoparticle-forming properties of associating in an aqueous solution, the pharmaceutical preparation composition having enhanced preparation stability. Particularly, a pharmaceutical preparation maintaining nanoparticle-forming properties, which are an important factor, and having an excellent storage stability is provided. Disclosed is a pharmaceutical preparation comprising a block copolymer in which a polyethylene glycol segment is linked to a polyglutamic acid segment containing a glutamic acid unit having a camptothecin derivative bonded thereto, the pharmaceutical preparation capable of forming associates in an aqueous solution. When the pharmaceutical preparation is made into an aqueous solution containing the camptothecin derivative at a concentration of 1 mg/mL, the pH of the aqueous solution is 2.4 to 7.0, and the change ratio of the associate-forming ability of the pharmaceutical preparation after storage at 40 C. for one week under light-blocked conditions is 50% or less.
Pharmaceutical formulations containing 3-(4-cinnamyl-l-piperazinyl) amino derivatives of 3-formylrifamycin SV and 3-formylrifamycin S and a process of their preparation
The present invention related to a process of preparation of pharmaceutically acceptable formulations containing as active substance 3-(4-cinnamy-1-piperazinyl)-amino derivatives of 3-formylrifamycine SV and 3-formylrifamycine S, which possess high activity against Gram-positive and Gram-negative microorganisms, as well as against tuberculous micobacteria (including atypical and rifamycin resistant), and to a method for the preparation of 3-(4-cinnamyl-1-piperazinyl)-amino derivatives of 3-formylrifamycine SV and 3-formylrifamycine S. The method for the preparation of pharmaceutical compositions is readily feasible, and does not require special equipment for its implementation. The process for preparing the compounds is characterized by high yield and purity, using an environmental clean solventethanol and water in the preparation and isolation of substances, and the absence of residual organic solvents in the final product.
CDK inhibitors
Compounds of formulae I, II or III, and pharmaceutically acceptable salts thereof, are useful as CDK inhibitors.
eIF4A-inhibiting compounds and methods related thereto
The present invention provides synthesis, pharmaceutically acceptable formulations and uses of compounds in accordance with Formula I, or a stereoisomer, tautomer or pharmaceutically acceptable salt thereof. ##STR00001##
For Formula I compounds X, Y, R.sup.1, R.sup.2, R.sup.3a, R.sup.3b, R.sup.4a, R.sup.4b and R.sup.5 are as defined in the specification. The inventive Formula I compounds are inhibitors of eIF4A and find utility in any number of therapeutic applications, including but not limited to treatment of inflammation and various cancers.
Lysophosphatidic acid detection
Embodiments of methods and compounds for isolating and detecting lysophosphatidic acids (LPAs) are disclosed. Kits for performing the methods also are disclosed. LPAs are isolated from biological samples by liquid-liquid extraction followed by solid phase extraction. LPA species may be separated by HPLC, and the separated species may be identified and quantified. Also disclosed are embodiments of compounds capable of universally detecting a plurality of LPA species with substantially equivalent sensitivity. Embodiments of the disclosed compounds are useful for determination of total LPA concentration in a sample comprising a plurality of LPA species without separation of individual LPA species.
Deuterated amlexanox
Provided herein is technology relating to deuterated amlexanox and particularly, but not exclusively, to compositions comprising deuterated amlexanox, methods of producing deuterated amlexanox, and uses of deuterated amlexanox.
