A continuous phytochemical study on the roots of Marsdenia tenacissima led to the isolation and identification of 13 new polyoxypregnane glycosides named marstenacissides B10-B17 (1, 2, 4, 7, 8, 11, 12, and 14) and marstenacissides A8-A12 (3, 9, 10, 13, and 15) in addition to two known polyoxypregnane glycosides marsdenosides M and L (5 and 6). Their structures were established by spectroscopic...
The medial portion of intrinsic buccal muscle 3 (I3m) is innervated by two excitatory motor neurons, B3 and B9. B3 uses glutamate as its fast transmitter and expresses the neuropeptide FMRFamide, whereas B9 uses acetylcholine as its fast transmitter and expresses the neuropeptide SCP. This preparation was used to study peptidergic modulation of muscles innervated by neurons that use different f...
