Proteasome inhibitors: Synthesis and activity of arecoline oxide tripeptide derivatives

We describe the synthesis and biological activities of a series of methyl 3,4-epoxypiperidine-3-carboxylate tripeptide derivatives that inhibit the chymotryptic and tryptic active sites of the 20S proteasome. Of the series, compound 2 which contains 3-hydroxy-2-methylbenzoyl group at its N-terminal position, displayed the greatest inhibitory potency (IC50 1 μM). All derivatives showed favourable pharmacokinetic properties.

Heterocyclic compounds

Novel piperidine compounds are provided, and those compounds are useful in the treatment and/or prevention of diabetes, and especially non-insulin dependent diabetes (NIDDM or type 2 diabetes) including overnight or meal treatment and treatment or prevention of longterm complications, such as retinopathy, neuropathy, nephropathy, and micro- and macroangiopathy; treatment of hyperglycemia, hypercholesterolemia, hypertension, hyperinsulinemia, hyperlipidemia, atherosclerosis or myocardial ischemia.

Azabicyclo quinolone carboxylic acids

Quinolone carboxylic acids 7-substituted by azabicyclo groups have antibacterial activity., Antibacterial wherein, R1 is hydrogen, a pharmaceutically acceptable cation, or alkyl;, Y, when taken independently, is ethyl, t-butyl, vinyl, cyclopropyl, 2-fluoroethyl, p-fluorophenyl, or o,p-difluorophenyl;, W is hydrogen, F, Cl, Br, alkyl, alkoxy, NH2, NHCH3;, A is CH, CF, CCl, COCH3, C-CH3, C-CN or N; or, A is carbon and is taken together with Y and the carbon and nitrogen to which A and Y are attached to form a five or six membered ring which may contain oxygen or a double bond, and which may have attached thereto R8 which is methyl or methylene; and, R2 is wherein R3, R4, R5, R6, R7, R9, R10 and R25 are each independently H, CH3, CH2NH2, CH2NHCH3 or CH2NHC2H5, and R5, R6, R7, and R9 may also independently be NH2, NHCH3 or NHC2H5.
