We have investigated whether exposure to tetradifon causes ovary injuries, disrupts folliculogenesis in rat and whether ovary hormones (estrogen and progesterone) to be affected by this endocrine-active agent. Female rats were exposed orally to a dose of 28.9 mg/kg/day for 6 or 12 weeks. After s...

The removal of chloropyrifos ethyl, tetradifon and chlorothalonil pesticide residues from the lemon, orange and grapefruit matrices were achieved by ozonation. All of chlorothalonil residues adsorbed onto the orange matrix were completely removed after 5 min ozonation. The highest removal percen...

The effects of subchronic exposure to tetradifon on biochemical related kidney toxicological parameters [creatinine (CRT), urea, and uric acid (UA)] were examined. Oxidative stress in kidney tissue was also assessed by measuring vitamin C (VitC) content and antioxidant enzyme activities [superox...

Post-stroke depression (PSD) is the most common mood disorder following a stroke, and is also the main factor limiting recovery and rehabilitation in stroke patients. The present study was aimed to investigate whether Huperzine A (HupA) has antidepressant-like activity in a rat model of PSD, whi...

Huperzine A (HupA) and Huperzine B (HupB) are natural alkaloids existed in Lycopodium plants. They both have potential clinical application for treating Alzheimer's Disease (AD). For the purpose of better utilizing the limited plant resources, a quick and low cost method to separate and pur...

Chemical warfare nerve agents such as soman exert their toxic effects through an irreversible inhibition of acetylcholinesterase (AChE) and subsequently glutamatergic function, leading to uncontrolled seizures. The natural alkaloid (−)-huperzine A is a potent inhibitor of AChE and has been demon...

The neuropathologic mechanisms after exposure to lethal doses of nerve agent are complex and involve multiple biochemical pathways. Effective treatment requires drugs that can simultaneously protect by reversible binding to the acetylcholinesterase (AChE) and blocking cascades of seizure related...

(−) Huperzine A is a bioactive alkaloid from Huperzia serrata (Lycopodiaceae) used for the treatment of Alzheimer's disease. High yielding (−) huperzine A species is of interest for mass propagation since it grows slowly in temperate countries. The content of (−) huperzine A from temperate ...

Five products were yielded from the transformation of (−)-Huperzine A (1) by Streptomyces griseus CACC 200300. Their structures were determined as 16-hydroxyl huperzine A (2), 14α-hydroxyl huperzine A (3), huperzine A 8α,15α-epoxide (4), 13N-formyl huperzine A (5), and 13N-acetyl huperzine A ...

Huperzine A has been used for improving symptoms of Alzheimer's disease. Its cholinergic side effect is thought to be an exaggerated pharmacological outcome linked to its high brain or CNS concentrations. Although Huperzine A is brain penetrable, its interaction with efflux transporters (AB...

Huperzine A (HupA) is a kind of Lycopodium alkaloid with potential disease-modifying qualities that has been reported to protect against β-amyloid (Aβ)-mediated mitochondrial damage in Alzheimer's disease. However, the fundamental molecular mechanism underlying the protective action of Hu...

BackgroundAlzheimer's Disease (AD) is associated with cognitive decline due to various pathological mechanisms. There are several acetylcholinesterase inhibitor compounds which can improve cognition, but Huperzine-A is a natural sesquiterpene alkaloid extracted from Chinese herb (Huperzia S...

Huperzine A loaded multiparticulate tablet with sustained release was developed to reduce dosing frequency and increase swallowing. The sustained release was provided by the ethyl cellulose/Poloxamer 127 (EC/F127) microparticles (MPs). F127 was added to facilitate drug release of EC MPs, and the...

Safranal, a dominant component of saffron, is known to have antitumor, cytotoxic, and antibacterial properties. In this study, we examined safranal and its structural analogs—thymol, carvacrol, damascenone, cuminol, 2,6,6-trimethyl-2-cyclohexene-1,4-dione (TMCHD), 4-isopropylbenzyl bromide (IPB...

Safranal, a monoterpene aldehyde, is present as one of the main volatile constituents of Crocus sativus Linn. (saffron flowers). This volatile constituent not only contributes to the aroma of saffron but has been reported to possess antidiabetic, antiulcer, antiasthamatic, anticonvulsant, antide...

Safranal is one of saffron constituents and has antioxidant and neuroprotective properties. Metformin is used as an anti-diabetic drug. This study was planned to investigate the separate and combined treatment effects of safranal and metformin on diabetes-induced learning and memory impairments ...

For determining the pharmacological properties of medicinal compounds, their binding with serum albumins is very crucial. Herein, we have selected safranal, a major constituent of saffron which is known to retain a number of medicinal properties including antioxidant, anti-inflammatory, tumorici...

Safranal is an organic compound isolated from saffron oil. Photo epoxidation and thermal reactions of safranal can be a significant tool for the design of drugs to act as anticancer agents and potent chemoprevention. Safranal was subjected to oxidation reactions either thermally using m-chlorope...

Safranal, a major constituent of saffron, possesses antioxidant and anti-apoptotic properties showing considerable neuroprotective effects. The present study was designed to investigate the effects of safranal against restraint stress induced oxidative damage in the rat brain. For inducing the c...

AimsSeveral natural products have been evaluated for management of gastric ulcer induced by non-steroidal anti-inflammatory drugs. Safranal, a plant-derived chemical, has a potent antioxidant and anti-inflammatory properties. The present study was aimed to evaluate possible gastro-protective eff...
