tested as penetrationenhancers in the diffusion of various drugs through hairless mouse skin in vitro. Hexamethylenelauramide (hexahydro-1-lauroyl-1H-azepine) was selected as a broad spectrum penetrationenhancer worthy of further study. Later, the duration of the effect of various enhancers on the penetration barrier in vivo was determined by evaluating the in vitro diffusion of hydrocortisone through
organometallic reagents has attracted the attention of organic chemists for a long time. However limited methods are reliable for common amides and have found synthetic applications. Here we report a method featuring in situ activation of tertiary amides with triflic anhydride (Tf2O) followed by addition of Grignardreagents. The method displays a good generality in scope for both amides and Grignard reagents
A composition useful for topically administering physiologically active agents through the skin and mucous membranes of humans and animals in a transdermal device or formulation for systemic use or to the skin of humans and animals for localized use comprising an effective amount of a physiologically active agent and a non-toxic, effective penetrating amount of a compound having the structural formula ##STR1## where R is an alkyl group with 1 to 19 carbon atoms, and m is 4, 5 or 6 is disclosed.

The present invention relates to the use of compounds as broad spectrum inhibitors of bacterial biofilm formation. In particular the invention refers to a family of compounds that block the quorum sensing system of Gram-negative and Gram-positive bacteria, a process for their manufacture, pharmaceutical compositions containing them and to their use for the treatment and prevention of bacterial damages and diseases, in particular for diseases where there is an advantage in inhibiting quorum sensing regulated phenotypes of pathogens.
