A capillary zone electrophoresis (CZE) method has been developed for investigating the physicochemical characteristics of five Strychnos alkaloids in Strychnos nux-vomica L. Firstly, the dissociation constants of the five Strychnos alkaloids were determined, based on the relation between the effective mobility of the solutes and the buffer pH. The mathematical relationship was strictly deduced ...

Some plants used in Unani system of medicine are toxic, even deadly poisonous. The drugs having such plants as their components are detoxified before they are dispensed to the patients. One such drug, capsule Hudar, has Strychnos nux-vomica L. (Azraqi) seeds as one of its components and is very effectively used to elevate blood pressure. Ancient manuscripts describe many methods of its detoxifi...

From cell suspension cultures of Ochrosia elliptica Labill. eight different monoterpenoid indole alkaloids were isolated and comprised three alkaloid classes viz. Corynanthe/Heteroyohimbine (tetrahydroalstonine, cathenamine, pleiocarpamine and two methoxylated heteroyohimbines), Strychnos (norfluorocurarine), Apparicine (apparicine and epchrosine). All these compounds except the Strychnos alkal...

Strychnos usambarensis Gilg (Loganiaceae) is one of thé three most widely distributed African species of Strychnos L. In East and South Africa thé plant grows as a small tree 3-15 m in height. In several other localities in East Africa, as well as in Zaïre, Congo, and West Africa, it is found as a climber up to 70 m long (1). The only other morphological différence between thé two forms is thé ...

The antidiabetic effect of seeds of Strychnos potatorum Linn. was evaluated in a model of diabetes mellitus using streptozotocin (40 mg/kg b.w., i.p.). Changes in fasting blood sugar were estimated periodically for 12 weeks along with weekly measurement of body weight, food and water intake for 4 weeks. The antidiabetic effects were compared with glipizide as the reference hypoglycemic drug. St...

Strychnos wallichiana (Loganiaceae) is a critically endangered medicinal plant, commonly used in several native medical practices. The majority of members of the Strychnos genus shares a similar chemical composition and contains common indole alkaloids. Purification of strychnine and brucine from a few species of Strychnos have already been reported; however, we have purified and quantified the...

Usually a moderately-sized liane, Slrychnos giiianemis (Aubl.) Martius occurs in forests, more especially along creeks and small rivers throughout thé middle and upper Rio Orinoco basin and entire Amazon basin (1). Among thé plants of thé Strychnos genus, this Slrychnos is known to be one of thé principal ingrédients of thé curare produced by numerous Indian tribes. This species contains a grou...

Natural products represent the fourth generation of multidrug resistance (MDR) reversal agents that resensitize MDR cancer cells overexpressing P-glycoprotein (Pgp) to cytotoxic agents. We have developed an effective synthetic route to prepare various Strychnos alkaloids and their derivatives. Molecular modeling of these alkaloids docked to a homology model of Pgp was employed to optimize ligan...
