A photoresponsive amphiphilic lipid molecule with phosphatidylcholine as the headgroup and a near-infrared (NIR) light-responsive unit on the hydrophobic moiety was synthesized. Liposomes constituting the NIR-responsive lipid, cholesterol and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, were constructed and applied as a photocontrolled release system. The precisely controlled release of the loaded cargo was demonstrated by adjusting the irradiation parameters and content of the photoresponsive species. The low cytotoxicity and good biocompatibility of the photoresponsive lipid was demonstrated by MTT assay. This study provides us with a new choice for developing a photoresponsive drug delivery system.

Paragraph 0045, (2017/01/23)
The invention relates to a preparation method for a carboxylic acid molecule, specifically to a photosensitive carboxylic acid molecule, and a preparation method and application thereof. According to the invention, 5-hydroxyl-nitrobenzaldehyde is used as a starting material to prepare o-nitrobenzyl-containing fatty acid through simple unit synthesis; light-degradable-unit-containing carboxylic acid is prepared through simple standard organic unit reactions like etherification, reduction and esterification; meanwhile, the method in the invention uses cheap raw materials and has simple synthetic process, so the photosensitive carboxylic acid molecule with different structures can be prepared with low cost; and an obtained target product can reach a level of hectogram and realize the purity of more than 98% through simple crystallization. In addition, the invention also discloses the application of the photosensitive carboxylic acid molecule in drug sustained release; meanwhile, drug-loading and photocontrolled release capacities of photosensitive phospholipid vesicles synthesized from light-degradable carboxylic acid prove that the photosensitive carboxylic acid molecule has good photoresponse performance.
Inhibitors of cyclic AMP phosphodiesterase. 1. Analogues of cilostamide and anagrelide

Evaluation of a series of lactam heterocyclic analogues of cilostamide as inhibitors of cyclic AMP phosphodiesterase derived from both human platelets and rat heart in comparison with their corresponding methoxy-substituted heterocycles has revealed that the N-cyclohexyl-N-methyl-4-oxybutyramide side chain of 2 is an important lipophilic and/or steric pharmacophore. Attachment of this side chain to the parent heterocycle of the potent cyclic AMP phosphodiesterase inhibitor anagrelide afforded the hybrid structure RS-82856, shown to be more potent than either of its progenitors as an inhibitor of cyclic AMP phosphodiesterase or of ADP-induced platelet aggregation. The available in vitro data suggest that 1 possesses potentially useful antithrombotic and cardiotonic properties.
