Caulilexin C is a phytoalexin from crucifers with antifungal activity[1].
Caulilexin C causes complete growth inhibition (0.5 mM) of Rhizoctonia solani and has a smaller effect on Leptosphaeria maculans (77% inhibition), appearing to be slightly more antifungal than arvelexin[1].

Interaction of cruciferous phytoanticipins with plant fungal pathogens: indole glucosinolates are not metabolized but the corresponding desulfo-derivatives and nitriles are
Phytochemistry 2011 Dec;72(18):2308-16.PMID:21920565DOI:10.1016/j.phytochem.2011.08.018.
Glucosinolates represent a large group of plant natural products long known for diverse and fascinating physiological functions and activities. Despite the relevance and huge interest on the roles of indole glucosinolates in plant defense, little is known about their direct interaction with microbial plant pathogens. Toward this end, the metabolism of indolyl glucosinolates, their corresponding desulfo-derivatives, and derived metabolites, by three fungal species pathogenic on crucifers was investigated. While glucobrassicin, 1-methoxyglucobrassicin, 4-methoxyglucobrassicin were not metabolized by the pathogenic fungi Alternaria brassicicola, Rhizoctonia solani and Sclerotinia sclerotiorum, the corresponding desulfo-derivatives were metabolized to indolyl-3-acetonitrile, Caulilexin C (1-methoxyindolyl-3-acetonitrile) and arvelexin (4-methoxyindolyl-3-acetonitrile) by R. solani and S. sclerotiorum, but not by A. brassicicola. That is, desulfo-glucosinolates were metabolized by two non-host-selective pathogens, but not by a host-selective. Indolyl-3-acetonitrile, Caulilexin C and arvelexin were metabolized to the corresponding indole-3-carboxylic acids. Indolyl-3-acetonitriles displayed higher inhibitory activity than indole desulfo-glucosinolates. Indolyl-3-methanol displayed antifungal activity and was metabolized by A. brassicicola and R. solani to the less antifungal compounds indole-3-carboxaldehyde and indole-3-carboxylic acid. Diindolyl-3-methane was strongly antifungal and stable in fungal cultures, but ascorbigen was not stable in solution and displayed low antifungal activity; neither compound appeared to be metabolized by any of the three fungal species. The cell-free extracts of mycelia of A. brassicicola displayed low myrosinase activity using glucobrassicin as substrate, but myrosinase activity was not detectable in mycelia of either R. solani or S. sclerotiorum.
Phytoalexins and polar metabolites from the oilseeds canola and rapeseed: differential metabolic responses to the biotroph Albugo candida and to abiotic stress
Phytochemistry 2008 Feb;69(4):894-910.PMID:18039546DOI:10.1016/j.phytochem.2007.10.019.
The metabolites produced in leaves of the oilseeds canola and rapeseed (Brassica rapa L.) inoculated with either different races of the biotroph Albugo candida or sprayed with CuCl(2) were determined. This investigation established consistent phytoalexin (spirobrassinin, cyclobrassinin, and rutalexin) and phytoanticipin (indolyl-3-acetonitrile, arvelexin, Caulilexin C, and 4-methoxyglucobrassicin) production in canola and rapeseed in response to both biotic and abiotic elicitation. In addition, a wide number of polar metabolites were isolated from infected leaves, including six new phenylpropanoids and two new flavonoids. The extractable chemical components of zoosporangia of A. candida and the anti-oomycete activity of phytoalexins were determined as well. Overall, the results suggest that during the initial stage of the interaction, leaves of B. rapa have a similar response to virulent and avirulent races of A. candida, with respect to the accumulation of chemical defenses. After this stage, despite the higher phytoalexin concentration, the "compatible" races could overcome the plant defense system for further infection, but growth of the "incompatible" races was inhibited. Since results of bioassays showed that cyclobrassinin and brassilexin were more inhibitory to A. candida than rutalexin, the apparent redirection of the phytoalexin pathway towards rutalexin, avoiding cyclobrassinin and brassilexin accumulation might be caused by the pathogen. Alternatively, A. candida might be able to detoxify both cyclobrassinin and brassilexin, similar to necrotrophic plant pathogens. Overall, the correlation between phytoalexin production in infected or stressed leaves and the outcome of the plant-pathogen interaction suggested that A. candida was able to elude the plant defense mechanisms by, for example, redirecting the phytoalexin biosynthetic pathway.
