Synthesis of diether-linked cationic lipids for gene delivery
Ren, Tan,Liu, Dexi
, p. 1247 - 1250 (2007/10/03)
Quaternary ammonium lipids 1b-d, with diether linkages between hydrocarbon chains and butane or hexane backbone, were synthesized for cationic liposome-mediated gene delivery. The synthetic strategy of using C- 4 or C-6 synthon permits the achievement of the variation of the hydrophobic domain as well as changes of space between the quaternary ammonium head and the hydrophobic domain in the diether-linked cationic lipids.
Enzyme-mediated enantioselective hydrolysis of cyclic carbonates
Matsumoto, Kazutsugu,Fuwa, Seiji,Kitajima, Hidehiko
, p. 6499 - 6502 (2007/10/02)
The enzyme-mediated enantioselective hydrolysis of cyclic carbonates is disclosed. Racemic 4-(2-benzyloxy)ethyl-1,3-dioxolan-2-one (1a) was enantioselectively hydrolyzed by porcine pancreas lipase (PPL) to give optically active (R)-1a and (S)-4-benzyloxybutane-1,2-diol (2a). PPL also catalyzed the hydrolysis of several five-membered cyclic carbonates with high enantioselectivity.
