Disulfide-containing peptides from the glandular skin secretions of froglets of the genus Crinia: structure, activity and evolutionary trends
{{output}}
The skin secretions of Crinia signifera, C. riparia and C. deserticola contain bioactive disulfide-containing peptides. Signiferin 1 (RLCIPYIIPC-OH) from C. signifera and C. deserticola) contracts smooth muscle at a concentration of 10(-9) M, and effects proli... ...
