Design, synthesis and identification of novel colchicine-derived immunosuppressant
摘要:
Synthesis and biological evaluation of various colchicine analogues through the mixed-lymphocyte reaction (MLR), lymphoproliferation, and inhibitory effects on the inflammatory genes are described. In addition, a new series of immunosuppressive agents developed on the structural basis of colchicine, as well as their structure-activity relationships is reported. The most potent analogue 20a exhibited an excellent immunosuppressive activity on in vivo skin-allograft model, which is comparable to that of cyclosporin A. (C) 2009 Elsevier Ltd.

Described herein are acyl germanium photoinitiator for cost-effective and time-efficient method for producing UV-absorbing contact lenses capable of blocking ultra-violet (“UV”) radiation and optionally (but preferably) violet radiation with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV radiation and potentially from violet radiation. This invention also provides a method for making UV-absorbing contact lenses made by using an acyl germanium photoinitiator of the invention.
