pederin pederin: isolated from beetles, Paederus fuscipes; minor descriptor (75-84); on-line & Index Medicus search PYRANS (75-84); RN given refers to (2S-(2alpha(R*(R*(2S*,5S*,6S*))),4beta,6beta(R*)))-isomer. pederin : A polyketide and carboxamide produced by a (Pseudomonas) bacterial endosymbiont of certain rove beetles (genus Paederus). Pederin is the agent responsible for the vesicant effects (linear or Paederus dermatitis) when the beetle is crushed against the skin. It is a powerful inhibitor of protein biosynthesis and mitosis and a potent antitumour agent. | 2.02 | 1 | 0 | cyclic ketal; diol; oxanes; polyketide; secondary alcohol; secondary carboxamide | antimitotic; antineoplastic agent; bacterial metabolite; vesicant |
bryostatin 1 bryostatin 1: a protein kinase C activator; macrocyclic lactone from marine Bryozoan Bugula neritina; RN given refers to (1S*-(1R*,3R*,5Z,7S*,8E,11R*,12R*(2E,4E),13E,15R*,17S*(S*),21S*,23S*,25R*))-isomer; structure given in first source; activates protein kinase c. bryostatin 1 : A member of the class of bryostatins that is (17E)-2-oxooxacyclohexacos-17-ene which is substituted by hydroxy groups at positions 4, 10, and 20; an acetoxy group at position 8; methyl groups at positions 9, 9, 18, and 19; 2-methoxy-2-oxoethylidene groups at positions 14 and 24; an (E,E)-octa-2,4-dienoyloxy group at position 21; and with oxygen bridges linking positions 6 to 10, 12 to 16, and 20 to 24. It is one of the most abundant member of the class of bryostatins. | 3.12 | 1 | 0 | | |
