Spiroguanidine rhodamines as fluorogenic probes for lysophosphatidic acid.
نویسندگان
چکیده
Direct determination of total lysophosphatidic acid (LPA) was accomplished using newly developed spiroguanidines derived from rhodamine B as universal fluorogenic probes. Optimum conditions for the quantitative analysis of total LPA were investigated. The linear range for the determination of total LPA is up to 5 μM with a limit of detection of 0.512 μM.

The century-old fluoresceins and rhodamines persist as flexible scaffolds for fluorescent and fluorogenic compounds. Extensive exploration of these xanthene dyes has yielded general structure-activity relationships where the development of new probes is limited only by imagination and organic chemistry. In particular, replacement of the xanthene oxygen with silicon has resulted in new red-shift...

Lysophosphatidic acid (LPA) known as a serum-derived growth factor, is involved in several cell physiological functions in the female reproductive system including: oocyte maturation, in vitro fertilization and embryo implantation by its transmembrane G protein-coupled receptors. The aim of the present study was to examine the effect of LPA on in vitro follicular development o...
