  • Publication number: 20060057234
    Abstract: The invention relates to a new use of a non-alkaloid compound that is plant derived glycoside ‘glycyrrhizin’ as a highly potent bio-enhancer of activity and availability of antibiotics and other drugs including anti-infective and anticancer agents. The molecule of invention facilitates the absorption/uptake of antibiotics and other molecules across the cell membrane in plant and animal cells as well as Gram-positive and Gram-negative bacteria and therefore can be used as a drug facilitator or bioenhancer molecule to increase the affectivity of drugs and nutraceutical agents. The compound having no antimicrobial or cytotoxic activity of its own, is a safe candidate to reduce the drug dosage towards circumventing the problem of drug resistance and the other side effects in anti-infective and anti-cancer therapies.

  • Patent number: 6858588
    Abstract: The present invention relates to a novel nitrile glycoside of Formula I named NIAZIRIDIN and to analogues and derivatives thereof. The present invention also relates to a process for the isolation of a novel nitrile glycoside of Formula I below named NIAZIRIDIN and its derivatives and analogues by bioactivity-guided fractionation from the pods of Moringa oleifera. The present invention particularly relates to the bioenhancing activity of the novel nitrile glycoside of Formula I below named NIAZIRIDIN and its derivatives and analogues in enhancing bioactivity of commonly used antibiotics such as rifampicin, tetracycline and ampicillin against Gram (+) and (?) bacteria. The biomolecule also enhances the absorption of drugs, vitamins and nutrients through the gastro-intestinal membrane increasing their bio-availability. Therefore niaziridin can be used in combination therapy with drugs and nutrients resulting in reduced drug associated toxicity, reduced cost and duration of chemotherapy.

  • Patent number: 4039907
    Abstract: A control circuit is provided for a linear induction motor to control motor thrust in relation to a reference thrust. An analog circuit, or computer, is supplied signals representative of the voltage and current to the motor. This analog circuit includes circuit elements simulating the stator or primary resistance of the motor, and it develops a control signal proportional to the power delivered to the motor less the copper losses in the primary resistance. This control signal is proportional to motor thrust if magnetizing losses and secondary resistance losses are ignored. A reference thrust signal is compared with this control signal, and the error between these two signals is used to control the firing angles of controlled rectifiers in a controlled rectifier bridge network supplying power to the motor. By this control loop the power supplied to the motor is regulated to control the thrust instantaneously developed in relation to a reference thrust.
