It has no cardiac effects.. digitonin : A spirostanyl glycoside that is digitogenin in which the 3-hydroxy group is substituted by a beta-D-glucopyranosyl-(1->3)-beta-D-galactopyranosyl-(1->2)-[beta-D-xylopyranosyl-(1->3)]-beta-D-glucopyranosyl-(1->4)-beta-D-galactopyranosyl group. It is a steroidal saponin isolated from the foxglove plant, Digitalis purpurea. It is used extensively as a mild non-ionic detergent for extracting proteins from membranes for structure and function studies. | 2.39 | 2 | 0 | | |

cyclic gmp
Cyclic GMP: Guanosine cyclic 3',5'-(hydrogen phosphate). A guanine nucleotide containing one phosphate group which is esterified to the sugar moiety in both the 3'- and 5'-positions. It is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin and it has been found to activate specific protein kinases. (From Merck Index, 11th ed). 3',5'-cyclic GMP : A 3',5'-cyclic purine nucleotide in which the purine nucleobase is specified as guanidine. | 2.37 | 2 | 0 | 3',5'-cyclic purine nucleotide;
