Abstract The well-known photosensitizers hypericin, harmane, and emodin are typical pigments of certain mushroom species—is this a coincidence or an indication towards photoactivated defense mechanism in the phylum Basidiomycota? This perspective article explores hypothesis by cross-linking chemistry fungal with structural requirements from known insights strategies kingdom Plantae. Thereby, li...
A new indole alkaloid; neonaucline (1), along with six known compounds-Cadamine (2), naucledine (3), harmane, benzamide, cinnamide and blumenol A-were isolated from the leaves of Ochreinauclea maingayii (Rubiaceae). In addition to that of compound 1, (13)C-NMR data of cadamine (2) and naucledine (3) were also reported. Structural elucidations of these alkaloids were performed using spectroscopi...
PURPOSE Peganum harmala L. (Zygophyllaceae) seeds extract is one of the main components of an ethnobotanical preparation used in the treatment of neoplasms in Iran. Cytotoxic effects of P. harmala extract on cancerous cell-lines have been reported before. beta-carbolines like harmaline and harmine are the major alkaloids present in the seeds of the P. harmala. Considering reports concerning DNA...
Over the past few years, a vast amount of research has shed light on the pharmacology of imidazoline binding sites (I-BS). To date, at least three classes of imidazoline binding sites have been characterised in accordance to their localisation, drug selectivity, proposed signalling pathways and functional roles. The existence of these sites raises the question as to whether an endogenous modula...
