Abstract

Dendrobine, considered as the major active alkaloid compound, has been used for the quality control and discrimination of Dendrobium which is documented in the Chinese Pharmacopoeia. In this work, a sensitive and simple ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method for determination of dendrobine in rat plasma is developed. After addition of caulophyline as an internal standard (IS), protein precipitation by acetonitrile-methanol (9:1, v/v) was used to prepare samples. Chromatographic separation was achieved on a UPLC BEH C18 (2.1 ×100 mm, 1.7 µm) column with acetonitrile and 0.1% formic acid as the mobile phase with gradient elution. An electrospray ionization source was applied and operated in positive ion mode; multiple reaction monitoring mode was used for quantification using target fragment ions m/z 264.2 → 70.0 for dendrobine and m/z 205.1 → 58.0 for IS. Calibration plots were linear throughout the range 2-1000 ng/mL for dendrobine in rat plasma. The RSDs of intra-day and inter-day precision were both <13%. The accuracy of the method was between 95.4 and 103.9%. The method was successfully applied to pharmacokinetic study of dendrobine after intravenous administration.

Abstract

1 The effects of dendrobine and nobiline, alkaloids isolated from Dendrobium nobile, on the electrical activity and on amino acid-induced depolarizations of primary afferent terminals were tested on the frog isolated spinal cord and were compared with those of picrotoxinin and strychnine. 2 Dendrobine (3 X 10(-5) M) caused a slight hyperpolarization in both dorsal and ventral roots and this hyperpolarization was accompanied by the augmentation of the dorsal root potential (DR-DRP) and the ventral root potential and reflex (DR-VRP and DR-VRR). The amplitude of the dorsal root reflex (DR-DRR) however, was reduced significantly. Nobiline (3 X 10(-5) M) had no significant effect on either the root potentials or the reflexes. 3 Dendrobine (3 X 10(-5) M) reduced the dorsal root potential induced by repetitive antidromic stimulation of ventral root (VR-DRP) as well as diminishing the maximum rate of rise of the dorsal root potential induced by the stimulation of adjacent dorsal roots (DR-DRP), during which time the amplitude of the DR-DRP was seen to be augmented. 4 Dendrobine (3 X 10(-5) M) reduced the beta-alanine- and taurine-induced depolarizations of primary afferent terminals, while having little effect upon GABA- and glycine-induced depolarizations. 5 Dendrobine (10(-5) M) reversibly blocked the presynaptic inhibition caused by antidromic conditioning stimulation of the ventral root. 6 These effects of dendrobine were qualitatively similar to those of strychnine but were somewhat different from those of picrotoxinin, a molecule having the same picrotoxane skeleton. 7 The present results are discussed with reference to the likely neurotransmitters involved in presynaptic inhibition in the frog spinal cord, and with respect to the structure-activity relationship of picrotoxane compounds as amino acid antagonists.

Abstract

Background: Lung cancer is a leading cause of cancer-related death worldwide. Cisplatin-based chemotherapy is the standard treatment for lung cancer, but chemoresistance and adverse effects especially cardiotoxicity limit its efficacy.
Purpose: The efficacy of combination treatment of dendrobine, a plant alkaloid isolated from Dendrobium nobile, with cisplatin was examined as a possible anti-non-small cell lung cancer strategy.
Methods: The cytotoxicity of dendrobine and cisplatin against A549 lung cancer cells was analyzed by MTT and colony formation assays. Apoptosis was measured by annexin V/PI double staining. Apoptosis-related proteins were assessed by western blotting and qPCR analysis. In vivo efficacy was determined using A549 xenograft in nude mice. JNK and Bim inhibition were achieved by siRNA knockdown and/or chemical inhibition. Cardiotoxicity was assessed by serum creatine phosphokinase activity assay.
Results: Dendrobine induced apoptotic cell death through mitochondrial-mediated pathway. Combination treatment of dendrobine with cisplatin showed enhanced cytotoxicity through stimulation of JNK/p38 stress signaling pathways and, consequently, the induction of apoptosis involving pro-apoptotic proteins Bax and Bim. In addition, dendrobine attenuated the body weight reduction and cardiotoxicity induced by cisplatin in nude mice.
Conclusion: The combination treatment showed enhanced anticancer activity toward non-small cell lung cancer cells without aggravating the cardiotoxic effects of cisplatin suggesting that the combination strategy deserves further investigation for human lung cancer treatment.
