Analogs of 8-[[6-(diethylamino)hexyl]amino]-6-methoxy-4-methylquinoline as candidate antileishmanial agents
摘要:
8-[[6-(Diethylamino)hexyl]amino]-6-methoxy-4-methylquinoline (I) has been shown to be highly effective against Leishmania donovani in hamsters, being approximately 475 times as active as the standard meglumine antimoniate. Several nuclear and side-chain analogues of I have been prepared in an attempt to further enhance the antileishmanial activity of this class of compounds. The compounds were tested against L. donovani in the golden hamster. Although several analogues had meglumine antimoniate indexes in excess of 300, none was superior to the model compound.
Topical therapeutic compositions are disclosed which contain from about 0.1 to 70 percent by weight of a water-soluble tertiary amine oxide and a therapeutic agent selected from the group consisting of erythromycin, benzoyl peroxide, hydrocortisone, tetracycline, 5-fluorouracil, and propranolol. The amine oxide enhances penetration of the therapeutic agent into and through the skin.

New ethylenically unsaturated monomers are provided that can be (co)polymerized to provide a composition and method whereby the same group that is attached to or within the backbone of an associative thickener is reversibly switched between being hydrophilic and hydrophobic in nature. When the group that is attached to or within the backbone is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this group is rendered hydrophobic, the thickener performs its thickening function efficiently. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened. The thickeners are prepared from the novel monomers by an aqueous solution polymerization.

A polymer composition with blocks of hydrophobes attached to or within the backbone of an associative thickener. The blocks are composed of two or more units of the same or different hydrophobes whereby the hydrophobe is reversibly switched between being hydrophilic and hydrophobic in nature. When the hydrophobe is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this hydrophobe is rendered hydrophobic, the thickener performs its thickening function efficiently, especially in tinted systems. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened.

Quaternary ammonium alkyl esters and thioesters of acidic nonsteroidal anti-inflammatory drugs (NSAIDs) are disclosed. These esters and thioesters display the anti-inflammatory profile of the parent NSAIDs with greatly reduced gastrointestinal irritancy, providing a more favorable separation of therapeutic activity and toxicological side effects than the parent NSAIDs.
