veratrum nigrum/항진균제

Steroidal alkaloids from Veratrum californicum (Durand) are known to exert teratogenic effects (e.g., cyclopia, holoprosencephaly) by blocking the Hedgehog (Hh) signaling pathway, which plays a considerable role in embryonic development and organogenesis. Most surprisingly, recent studies

The heart is an aerobic organ, and most of the energy required for the contraction and maintenance of ion gradients comes from oxidative phosphorylation. Oxidative stress caused by free radicals plays a crucial role in the pathophysiology associated with atherosclerosis, neoplasia and

BACKGROUND The pharmacological effect derived from herb-herb interaction is important to constitute the prescription especially in traditional oriental medicine. The relationship of two medicinal herbs is called "couplet medicinals" which is used in pair for the purpose of enhancing the therapeutic

Several species of the Veratrum genus are associated with toxicity in humans and animals. The principal toxins are steroid alkaloids; some have a modified steroid template, whereas others differ in their esterified acid moieties. These alkaloids act by increasing the permeability of the sodium

BACKGROUND We report a case of digoxin-like toxicity because of ingestion of foraged plants. This patient presented with nausea, vomiting, bradycardia, and hypotension after ingesting Veratrum viride (false hellebore). The patient's serum specimen demonstrated a positive digoxin level (0.38 ng/mL)

Non-small cell lung cancer (NSCLC) has been identified as a leading cause of tumor-associated death around the world. Presently, it is necessary to find effective and safe therapy for its treatment in clinic. Jervine (Jer), a sterodial alkaloid from rhizomes of Veratrum album, exhibits

Steroid alkaloids have been shown to elicit a wide range of pharmacological effects that include anticancer and antifungal activities. Understanding the biosynthesis of these molecules is essential to bioengineering for sustainable production. Herein, we investigate the biosynthetic pathway to

Ethanol is a principle ingredient of alcoholic beverages with potential neurotoxicity and genotoxicity, and the ethanol-associated oxidative DNA damage in the central nervous system is well documented. Natural source compounds may offer new options to protect the brain against ethanol-induced

Resveratrol, trans-3,5,4'-trihydroxystilbene, was first isolated in 1940 as a constituent of the roots of white hellebore (Veratrum grandiflorum O. Loes), but has since been found in various plants, including grapes, berries and peanuts. Besides cardioprotective effects, resveratrol exhibits

Veratrum maackii (VM), a perennial plant in the Melanthiaceae family, has anti-hypertensive, anti-cholinergic, anti-asthmatic, anti-tussive, anti-fungal, anti-melanogenesis, and anti-tumor activities. Here, we investigated the therapeutic effect of VM on benign prostatic hyperplasia (BPH) in human

Covering: 1950s to 2015During the 1950s, sheep ranchers in the western United States experienced episodic outbreaks of cyclopic lambs. In this highlight I describe how these mysterious incidents were traced to the grazing of Veratrum californicum wildflowers by pregnant ewes, leading to the

The hedgehog (Hh) signaling pathway is an important therapeutic target in cancer; involvement of the Hh pathway has been shown in a variety of cancers including basal cell carcinoma, medulloblastoma, leukemia, and gastrointestinal, breast, prostate, lung, and pancreatic cancers [1-10]. Currently,

Phytochemicals are constitutive metabolites that enable plants to overcome temporary or continuous threats integral to their environment, while also controlling essential functions of growth and reproduction. All of these roles are generally advantageous to the producing organisms but the inherent
