Phosphorylation-dependent protein-protein interaction has rarely been targeted in medicinal chemistry. Thymoquinone, a naturally occurring antitumor agent, disrupts prephosphorylated substrate recognition by the polo-box domain of polo-like kinase 1, a key mitotic regulator responsible for various carcinogenesis when overexpressed. Here, crystallographic studies reveal that the phosphoserine/ph...

Platelets are small circulating anucleated cells, resulting from the fragmentation of megakaryocytes. They directly involved in primary hemostasis, where they among first elements to intervene stopping bleeding. Platelet count or functional alteration was reported be correlated different types diseases. Since antiquity, plants have been used cure panoply Nigella sativa, black cumin, is an annua...

The present study investigated the protective effect of thymoquinone (TQ), against cadmium-induced kidney injury in rats. Cadmium chloride (1.2 mg Cd/kg/day, s.c.), was given for nine weeks. TQ treatment (40 mg/kg/day, p.o.) started on the same day of cadmium administration and continued for nine weeks. TQ significantly decreased serum creatinine, renal malondialdehyde and nitric oxide, and sig...

objective(s): for determining the mechanism of anti-asthmatic effect of thymoquinone, this investigation evaluated the effect of thymoquinone in the presence of selective a2a and a2b adenosine receptor antagonists (zm241385 and mrs1706, respectively). materials and methods: seventy guinea pigs were randomly divided to 7 groups; control (c), sensitized with ovalbumin (s), sensitized groups pretr...

The laid out...

objective: the incidence and prevalence of kidney stone is increasing worldwide. after the first recurrence the risk of subsequent relapses is higher and the time period between relapses is shortened. urinary stones can be severely painful and make a huge economic burden. the stone disease may increase the vulnerability of patients to other diseases such as renal failure. medicinal herbs are ri...

objective(s): glioblastoma multiforme (gbm) is one of the most lethal forms of human cancer and temozolomide (tmz) is currently part of the standard treatment for this disease. combination therapy using natural substances can enhance the anti-cancer activity of tmz. the purpose of this study was to evaluate the effect of tmz in combination with thymoquinone (tq) on human gbm cell line (u87mg). ...
