due to the low heat output of lamps and the reaction rates using 110 W of CFL were slower but comparable to those obtained using a 500 W tungsten halogen lamp. The conditions were applied to the photooxidation of a series of furan aldehydes and 1,3-butadienes to give products in good yield in 4–96 hours.
节能紧凑型荧光灯 (CFL) 已被评估为用于敏化产生单线态氧的光源,该单线态氧用于使用一系列染料(包括玫瑰红、亚甲蓝和四苯基卟啉)氧化 1,3-丁二烯和糠醛衍生物. 由于灯的低热输出,环境温度水套足以冷却反应混合物,使用 110 W CFL 的反应速率较慢,但与使用 500 W 卤钨灯获得的反应速率相当。将该条件应用于一系列呋喃醛和 1,3-丁二烯的光氧化,以在 4-96 小时内以良好的产率得到产品。

Vesicular glutamate transporters (VGLUTs) allow the loading of presynaptic glutamate vesicles and thus play a critical role in glutamatergic synaptic transmission. Rose Bengal (RB) is the most potent known VGLUT inhibitor (K-i 25 nM); therefore we designed, synthesized and tested in brain preparations, a series of analogs based on this scaffold. We showed that among the two tautomers of RB, the carboxylic and not the lactonic form is active against VGLUTs and generated a pharmacophore model to determine the minimal structure requirements. We also tested RB specificity in other neurotransmitter uptake systems. RB proved to potently inhibit VMAT (K-i 64 nM) but weakly VACHT (K-i > 9.7 mu M) and may be a useful tool in glutamate/acetylcholine co-transmission studies. (C) 2010 Elsevier Ltd.
