Anti-tumor Promoting Activity of Bufadienolides from Kalanchoe pinnata and K. daigremontiana × butiflora
TLDR
Results strongly suggest that bufadienolides are potential cancer chemopreventive agents.
New Insecticidal Bufadienolide, Bryophyllin C, from Kalanchoe pinnata
TLDR
Two insecticidal bufadienolides were isolated from a methanol extract of the leaves of Kalanchoe pinnata by bioassay-guided fractionation and showed strong insecticidal activity against third instar larvae of the silkworm.
Pseudovitamin B(12) is the predominant cobamide of an algal health food, spirulina tablets.
The vitamin B(12) concentration of an algal health food, spirulina (Spirulina sp.) tablets, was determined by both Lactobacillus leichmannii ATCC 7830 microbiological and intrinsic factor
New Convulsive Compounds, Brasiliamides A and B, from Penicillium brasilianum Batista JV-379
TLDR
New convulsive compounds, brasiliamides A and B, were isolated by activity-guided fractionation from okara fermented with a soil isolate of Penicillium brasilianum Batista JV-379 and showed convulsive activity against silkworms with ED50 values of 300 and 50 μg/g of diet.
New Brasiliamide Congeners, Brasiliamides C, D and E, from Penicillium brasilianum Batista JV-379
TLDR
Three new brasiliamide congeners were isolated from okara fermented with Penicillium brasilianum Batista JV-379 and showed convulsive activity against silkworms and NMR spectra exhibited a mixture of four or two conformers due to the restricted rotation of an amide bond in a solution.
Two Jasmonoid Glucosides and a Phenylvaleric Acid Glucoside from Perilla frutescens
Three new glucosidic constituents (1–3) were isolated from the methanolie extract of Perilla frutescens. Two of these compounds (t and 2) were jasmonoid glucosides and were determined to be
