Enantiomeric synthesis of natural alkylglycerols and their antibacterial and antibiofilm activities

Alkylglycerols (AKGs) are bioactive natural compounds that vary by alkyl chain length and degree of unsaturation, and their absolute configuration is 2S. Three AKGs (5l–5n) were synthesised in enantiomerically pure form, and were characterised for the first time together with 12 other known and naturally occurring AKGs (5a–5k, 5o). Their structures were established using 1H and 13C APT NMR with 2D-NMR, ESI-MS or HRESI-MS and optical rotation data, and they were tested for their antibacterial and antibiofilm activities. AKGs 5a–5m and 5o showed activity against five clinical isolates and P. aeruginosa ATCC 15442, with MIC values in the range of 15–125 μg/mL. In addition, at half of the MIC, most of the AKGs reduced S. aureus biofilm formation in the range of 23%–99% and P. aeruginosa ATCC 15442 biofilm formation in the range of 14%–64%. The antibiofilm activity of the AKGs assessed in this work had not previously been studied.

Lipid Compounds Targeting VLA-4

The invention relates to the compounds of formula I: and pharmaceutically acceptable salts and esters thereof, wherein n, G, W, X, Y, and R1 are defined in the detailed description and claims. The compounds of formula I bind to or associate with VLA-4 and can be used in delivery formulations to deliver drugs, nucleic acids, or other therapeutic compounds to tissues or cells expressing VLA-4.

Synthesis, critical micelle concentrations, and antimycobacterial properties of homologous, dendritic amphiphiles. Probing intrinsic activity and the "cutoff" effect

Newkome-type, 1→3 C-branched dendrons make an excellent headgroup for amphiphiles with ultralong, saturated, linear alkyl chains. Synthesis of a homologous series of five such amphiphiles from 14 to 22 carbons- RNHCONHC(CH2CH2CO2H)3, R = n-C nH2n+1, n = 14, 16, 18, 20, 22-proceeds readily. These amphiphiles are soluble in aqueous solutions of triethanolamine. Surface-tension measurements on this homologous series reveal an unusually gradual decrease in log critical micelle concentration (CMC) as the chain length increases. In fact, the tetradecyl homologue does not appear to form micelles. Further, measurements of minimal inhibitory concentration (MIC) by broth microdilution against Mycobacterium smegmatis as a function of the initial cell density provide a direct measure of the intrinsic activity (MIC0) of each homologue. The hexadecyl homologue is the most active at inhibiting growth with an MIC0 equal to 3.5 × 10-5 M, which is 100-fold below the CMC.

N-substituted glycerophosphoethanolamines

The present invention relates to novel, therapeutically active fatty alkyl and alkenyl ether glycerophospholipids bearing a 3-(2-imidazolinyl)-2-imidazolinyl or 2-imidazolinyl substituent on the ethanolamine nitrogen, methods of using the compounds and pharmaceutically acceptable salts thereof, and pharmaceutical compositions containing same. The novel, therapeutically active compounds and salts of the invention possess anti-tumor, anti-psoriatic, anti-inflammatory, and anti-asthma activities.
