In-vitro-Versuche mit radioaktiv markiertem Cholesterin zeigen, das Cholesterin durch das Sekret aus den Hautdrusen von Salamandra maculosa maculosa in die darin vorkommenden Alkaloide umgewandelt wird. 
Über Samandarin und verwandte Alkaloide, XIX1)Konstitution und Synthese des Samanins
Aus dem Hautdrusensekret von Salamandra maculosa taeniata wird ein weiteres Alkaloid, Samanin, isoliert, durch Massen- und IR-Spektren in seiner Struktur als 16β-Hydroxy-3-aza-A-homo-5β-androstan (1)Expand
Variability of alkaloids in the skin secretion of the European fire salamander (Salamandra salamadra terrestris).

TLDR
The two major alkaloids, samandarine and samandarone, were identified in the skin secretion of individual specimens from two populations of the European fire salamander by gas chromatography/mass spectrometry suggesting separate metabolic pathways of the compounds. Expand
Biosynthesis of cholesterol and cholesterol acetate in dendrobatid arrow poison frogs.
TLDR
The biosynthesis of these poisons has now been investigated in Dendrobates pumilio, D. auratus and Phyllobates aurotaenia, using as possible precursors radioactive cholesterol, mevalonate and acetate, which converted to cholesterol and cholesterol acetate. Expand
Discovery of skin alkaloids in a miniaturized eleutherodactylid frog from Cuba
TLDR
Analyses of stomach content indicated a numerical prevalence of mites with an important proportion of oribatids—a group of arthropods known to contain one of the pumiliotoxins detected in E. iberia, suggesting that miniaturization and specialization to small prey may have favoured the acquisition of dietary skin alkaloids in these amphibians.

Biosynthesis of pregnane derivatives.
TLDR
This chapter focuses on the type of C 21 steroids isolated, their distribution, their precursors and steroids closely related to them, and the distribution of the enzymes concerned with their formation. Expand
Secondary Plant Substances
Phenylalanine and tyrosine give rise to many secondary plant products. Phenylalanine is preferably converted to cinnamic acid, the parent substance of the large group of nonnitrogenousExpand
ARTHROPOD ALKALOIDS IN POISON FROGS : A REVIEW OF THE 'DIETARY HYPOTHESIS'
Poison frogs are chemically defended from predators and/or microorganisms by the presence of alkaloids in dermal skin glands. Over the past 40 years, more than 800 alkaloids, which are generallyExpand
Chapter 5 Amphibian Alkaloids
TLDR
This chapter describes the novel amphibian toxins, their isolation, structure, and syntheses, the phenomenon of receptors that selectively bind to specific agents, the location and function of amphibious venoms; spiropiperidines, cis -decahydroquinolines, and octahydrodotoxin; neurotoxins, receptors, and ion transport. Expand
Terpenoid and Steroid Alkaloids
The diverse group of natural products classed as terpenoids and steroids includes some compounds that contain nitrogen and are called alkaloids on that account. Biosynthetically they can be set apartExpand
