The toxicity to cattle and bufadienolide content of six Bryophyllum species.
It has to be noted that, compared to cinnamic acids and flavonoids, most bufadienolides show lower UV absorbances (low [epsilon] values) at the detection wavelength of 298 nm.
Antitumor agents, 1101,2 bryophyll in B, a novel potent cytotoxic bufadienolide from Bryophyllum pinnatum.
Structure and stereochemistry of bryophyllin-A, a novel potent cytotoxic bufadienolide orthoacetate from Bryophyllum pinnatum.
2% (1 mg/ml) while the bufadienolide
fraction had no inhibitory effect in the investigated concentrations.
New insecticidal bufadienolide
, bryophyllin C, from Kalanchoe pinnata.
An endogenous bufadienolide
inhibitor of sodium pump, marinobufagenin, has also been shown to be increased in HF, and its plasma concentrations seem to correlate with severity of disease (65).
Preliminary data suggest that the bufadienolide
content in the chewable tablets used in the present study was less than 0.
is synthesized from cholesterol in the adrenal cortex by a pathway that is independent of cholesterol side-chain cleavage.
pinnatum have been conducted which led to the identification of bufadienolides
(Yamagishi et al.
Simultaneous determination of cytotoxic bufadienolides
in the Chinese medicine ChanSu by high-performance liquid chromatography coupled with photodiode array and mass spectrometry detections.
Since the island has no poisonous toads, Mori proposed that the snakes need to eat toads to have the defensive toxins, called bufadienolides
