Glands, digestive

Murexine and related compounds have marked actions on the nicotine receptor as expected from choline esters (87-89). Toxins from the digestive glands of nudi-branchs have marked effects on the cardiovascular system of the rat (23). Antiviral and antibacterial substances have been obtained from molluscs (90,91).

Labelled mevalonic acid dibenzylethylenediamine (DBED) salt (14 pCi) was injected into the digestive glands of D. limbata [90]. After 24 h, the animals were sacrificed and labelled polygodial (30) was recovered from the skin of the mollusc. After two subsequent chromatographic purifications, the dialdehyde was reduced to the corresponding diol (35) which was significantly labelled. The ability of D. limbata to synthesize de novo its own defensive allomone raised a series of questions linked to... 

In order to investigate whether the above glycerides are derived from the animal s diet or by biosynthesis, [2-14C]RS-mevalonic add DBED salt was injected into the digestive gland of A. montereyensis and A. odhneri spedmens, which were placed in a running sea-water aquarium for 24 h and then extracted [79]. Incorporation of the label was checked in the major metabolites of the two nudibranchs, namely 23 and 51 in A. montereyensis and 47 in A. odhneri, after HPLC purification and conversion to derivatives that were also purified via...
