ABSTRACT
A series of novel 1-(1-benzoylpiperidin-4-yl) methanamine derivatives were synthesized and evaluated for the serotonin reuptake inhibitory abilities and binding affinities to the 5-HT1A receptor. The metabolic stabilities of these compounds were measured in vitro using human or mouse liver microsomes and the antidepressant activities were explored In vivo using the forced swimming test (FST) and tail suspension test (TST) in mice. The results indicated that the compound 12a exhibited strongest serotonin reuptake inhibition (IC50 = 8.2 nM) and marked 5-HT1A receptor affinity (Ki = 0.069 nM), which were significantly superior to lead compounds â and â ¡. Meanwhile, compound 12a showed good metabolic stability in vitro and exhibited potential antidepressant-like effects in the FST and TST in mice.

OBJECTIVE: To speed up seedling production of pasqueflower (Puzlsatilla chinenses) and their modernization in pasqueflower. METHOD: With tissue culture method, primary culture of different explants, culture of cluster buds and their rooting culture were conducted on medium of treatment combinations of adding different hormones. RESULT: The appropriate medium for different culture stages were MS + 6-BA 1.0-3.0 mg x L(-1) + NAA 0-0.05 mg x L(-1) + Sucrose 30 g x L(-1) in primary culture, MS + 6-BA 0.2 mg x L(-1) + NAA 0.02 mg x L(-1) + BR 0.00001 mg x L(-1) + Sucrose 30 g x L(-1) in differentiation and subculture of cluster buds, 1/2 MS + NAA 0.4 mg x L(-1) + Sucrose 20 g x L(-1) in rooting. CONCLUSION: Applying stem tip and flower buds as explants, high frequency propagation of seedlings can be achieved with plant tissue culture in Pasqueflower.
