Imidazole Analogues of Fluoxetine, a Novel Class of Anti-Candida Agents
摘要:
Imidazole analogues of fluoxetine have been obtained by replacing the methylamino terminus of aminopropane chain with the imidazole ring. The newly designed imidazoles showed potent anti-Candida activity, superior to those of miconazole and other antifungal agents of clinical interest. 1-(4-Chlorophenyl)-1-(2,4-dichlorophenoxy)-3-(1H-imidazol-1-yl)propane (16), the most active among test imidazoles, was about 2-fold more active and as much less cytotoxic than miconazole. High increase of activity was observed with methyl, nitro, fluorine, and chlorine (Cl > F > CH3 > NO2 > CF3).

We describe the first electrochemical activation of D–A cyclopropanes and D–A cyclobutanes leading after C(sp3)−C(sp3) cleavage to the formation of highly reactive radical cations. This concept is utilized to formally insert molecular oxygen after direct or DDQ-assisted anodic oxidation of the strained carbocycles, delivering β- and γ-hydroxy ketones and 1,2-dioxanes electrocatalytically.

With a coat for activity: A highly active enzyme was prepared by coating Burkholderia cepacia lipase with an ionic surfactant for use in dynamic kineticresolution (DKR). Important features of this enzyme include: the fastest DKR of 1‐phenylethanol, the highlyenantioselective DKR of a wide range of secondary alcohols (RCH(OH)Ar), and the switching of lipase enantioselectivity in DKR depending on the shape
complementary procedures were adopted for preparing 2-arylazetidine derivatives in moderate to good yields. Preliminary biological evaluation of 2-arylazetidines as ligands of nicotinic acetylcholine receptors allowed to identify chloro-substituted analogs as the most interesting congeners. The title compounds may be considered as suitable hit compounds for developing new nicotinic acetylcholine receptor
Regioselective functionalization of 2-arylazetidines: evaluating the ortho-directing ability of the azetidinyl ring and the α-directing ability of the N-substituent
The regioselective lithiationâfunctionalization of 2-arylazetidines has been explored. The nature of the N-substituent is mainly responsible for a regioselectivity switch. ortho-Lithiation occurred, using hexyllithium as a greener base, in N-alkylazetidines, while α-benzylic lithiation has been observed with N-Boc azetidines.
