Thymoquinone (TMQ) is reported with good anti-psoriatic activity however, the hydrophobicity, poor aqueous solubility, light and pH sensitive nature of TMQ hinder its delivery to target site. To address these delivery challenges of TMQ, lipospheres were explored. The topical use of lipospheres offer an effective mean of penetration along with stability and scalability. TMQ lipospheres of particle size below 70nm were prepared and evaluated. These lipospheres resulted in deeper skin penetration, slow release and skin compatibility...

Thymoquinone is a known inhibitor of neuroinflammation. However, the mechanism(s) involved in its action remain largely unknown. In this study, we investigated the roles of cellular reactive oxygen species (ROS), 5' AMP-activated protein kinase (AMPK) and sirtuin 1 (SIRT1) in the anti-neuroinflammatory activity of thymoquinone. We investigated effects of the compound on ROS generation in LPS-activated microglia using the fluorescent 2',7'-dichlorofluorescin diacetate (DCFDA)-cellular ROS detection. Immunoblotting was used to detect protein levels of p40(phox), gp91(phox), AMPK, LKB1 and SIRT1...

BACKGROUND: Thymoquinone (TQ) is a potent cytoprotective, antioxidant and anti-inflammatory agent. We aimed to investigate the possible protective effects of TQ on survival, mesenteric artery blood flow (MABF), vascular reactivity, oxidative and inflammatory injuries in a murine sepsis model induced by cecal ligation and puncture (CLP). METHODS: Wistar rats were divided into the following four groups: Sham, CLP, Sham+TQ and CLP+TQ. TQ (1mg/kg/day) or vehicle (dimethyl sulfoxide, 1mL/kg/day) was intraperitoneally injected for 3 days...

BACKGROUND: Human tuberculosis, which is caused by the pathogen Mycobacterium tuberculosis, remains a major public health concern. Increasing drug resistance poses a threat of disease resurgence and continues to cause considerable mortality worldwide, which necessitates the development of new drugs with improved efficacy. Thymoquinone (TQ), an essential compound of Nigella sativa, was previously reported as an active anti-tuberculosis agent. METHODS: In this study, the effects of TQ on intracellular mycobacterial replication are examined in macrophages...

Oxidative stress plays an important role in both the initiation and progression of Parkinson's disease (PD). Rotenone, an environmental toxin, induces oxidative stress and impact mitochondrial dynamics, including fission and fusion. Thymoquinone (TQ) has been reported to have antioxidant and anti-inflammatory characteristics in vitro and in vivo. TQ scavenges free radicals so prevents cell damage against oxidative agents. To evaluate the efficacy of TQ in the management of PD, male Wistar rats (8-10 months) received rotenone...

For almost a decade, there has been much interest in the development of chemical inhibitors of Polo-like kinase 1 (Plk1) protein interactions. Plk1 is a master regulator of the cell division cycle that controls numerous substrates. It is a promising target for cancer drug development. Inhibitors of the kinase domain of Plk1 had some success in clinical trials. However, they are not perfectly selective. In principle, Plk1 can also be inhibited by interfering with its protein interaction domain, the Polo-Box Domain (PBD)...

The buttercup family, Ranunculaceae, comprising more than 2,200 species in at least 62 genera, mostly herbs, has long been used in folk medicine and worldwide ethnomedicine since the beginning of human civilization. Various medicinal phytometabolites have been found in Ranunculaceae plants, many of which, such as alkaloids, terpenoids, saponins, and polysaccharides, have shown anti-cancer activities in vitro and in vivo. Most concerns have been raised for two epiphany molecules, the monoterpene thymoquinone and the isoquinoline alkaloid berberine...

AIMS: Sodium nitrite is a widely used color fixative and preservative. However, it has been reported to exert deleterious toxic effects on various body organs. Moreover, thymoquinone (TQ), the active constituent of Nigella sativa oil is known to possess beneficial antioxidant and anti-inflammatory effects. The present study was conducted to evaluate the potential protective effects of TQ against sodium nitrite-induced renal toxicity. MAIN METHODS: Male Sprague-Dawley rats were treated with sodium nitrite (80mg/kg, po, daily) in presence or absence of TQ (25 and 50mg/kg, po, daily)...

Thymoquinone is an anticancer phytochemical commonly found in black cumin. In this review, we discuss the potential of thymoquinone as anticancer molecule, its mechanism of action and future usage in clinical applications. Thymoquinone exhibits anticancer activity via numerous mechanisms of action, specifically by showing selective antioxidant and oxidant activity, interfering with DNA structure, affecting carcinogenic signaling molecules/pathways and immunomodulation. In vitro activity of thymoquinone has been further implicated in animal models of cancer; however, no clinical application has been proven yet...

Thymoquinone (TQ) is a poorly water soluble bioactive compound which shows poor oral bioavailability upon oral administration. Due to poor aqueous solubility and bioavailability of TQ, various self-nanoemulsifying drug delivery systems (SNEDDS) of TQ were developed and evaluated for enhancement of its hepatoprotective effects and oral bioavailability. Hepatoprotective and pharmacokinetic studies of TQ suspension and TQ-SNEDDS were carried out in rat models. Different SNEDDS formulations of TQ were developed and thermodynamically stable TQ-SNEDDS were characterized for physicochemical parameters and evaluated for drug release studies via dialysis membrane...

Thymoquinone (TQ), a major bioactive compound of Nigella sativa seeds has several therapeutic properties. The main drawback in bringing TQ to therapeutic application is that it has poor stability and bioavailability. Hence a suitable carrier is essential for TQ delivery. Recent studies indicate biodegradable polymers are potentially good carriers of bioactive compounds. In this study, polyethylene glycol (PEG) modified chitosan (Cs) nanocapsules were developed as a carrier for TQ. Aqueous soluble low molecular weight Cs and PEG was selected among different biodegradable polymers based on their biocompatibility and efficacy as a carrier...

Status epilepticus (SE), which can cause neuronal injury, neuronal death and alteration of neuronal networks, is characterized by high mortality and morbidity. Recently, inflammation was shown to play a significant role in SE pathogenesis. We also found that microRNA-146a was highly expressed in SE rats with severe inflammation. The role of miRNA-146a in the inflammatory response of SE is not clear. Thus, in our study, we investigated the relationship between inflammation and miR-146a expression. We assessed the effects of thymoquinone, an anti-inflammatory drug, and found it had a neuroprotective effect on SE by inhibiting the inflammatory reaction...

Human salivary aldehyde dehydrogenase (hsALDH) is a very important anti-oxidant enzyme present in the saliva. It is involved in the detoxification of toxic aldehydes and maintenance of oral health. Reduced level of hsALDH activity is a risk factor for oral cancer development. Thymoquinone (TQ) has many pharmacological activities and health benefits. This study aimed to examine the activation of hsALDH by TQ. The effect of TQ on the activity and kinetics of hsALDH was studied. The binding of TQ with the enzyme was examined by different biophysical methods and molecular docking analysis...
