Quest PharmaTech Announces Strategic Alliance with IntelligentNano
News Apr 07, 2009
Quest PharmaTech Inc. has announced that it has formed a strategic alliance with IntelligentNano Inc. and, as a result of the alliance, the two groups have created a water soluble nano-formulation of Quest's SL052 technology, which has the potential to address a wider range of clinical needs than Quest's current formulation of SL052.
"We have successfully used nanoparticles to make SL052 water soluble while maintaining the biological activity of the drug, whether activated by light or ultrasound," said Dr. Jie Chen, Chief Technology Officer for IntelligentNano, a spin-off company from the Canadian National Research Council's National Institute for Nanotechnology.
"The fulfillment of a second tier of targetable, water-soluble nano-formulations of the SonoLight compounds represents major progress in the adaptation of Hypocrellin-based photodynamic and sonodynamic therapy to a wide spectrum of clinical needs including cancer treatment," stated Dr. Madi R. Madiyalakan, Chief Executive Officer at Quest.
The alliance between Quest and IntelligentNano was forged to explore the potential of nanotechnology to provide a multiplicity of biocompatible drug delivery systems for clinical applications of Quest's proprietary SonoLight technology platform. Current SonoLight photosensitizer and sonosensitizer formulations are based upon liposomal drug delivery systems which target the drug to the desired sites of photodynamic or sonodynamic therapies. Quest intends to initiate a series of preclinical studies with these new formulations and arrive at a clinical plan for Quest's second cancer indication.
The results from the product development initiative will be presented at the prestigious Institute of Electrical and Electronics Engineers, Inc. /National Institute of Health conference (IEEE/NIH) to be held on April 9, 2009 at the National Institute of Health in Maryland, USA.
The strategic alliance between Quest and IntelligentNano was made possible by financial and strategic support from the National Research Council's Industrial Research Assistance Program (NRC-IRAP).
Quest also announced that it has received a one-year extension for the repayment of its $500,000 convertible debenture. The repayment of the debenture, which is exercisable at $0.25 per common share, was originally due on March 22, 2009.
Researchers Develop Novel ‘One-pot’ Approach to Conjugated Tetraenes SynthesisNews
TUAT researchers have achieved the new synthetic route of conjugated tetraenes from inexpensive and easily available 1,3-butadiene and substituted acetylenes by a one-pot approach under mild conditions. Conjugated tetraenes are important key substructures in biologically active natural products such as vitamins, and anti-mycotic drugs.READ MORE
Gecko Toes Inspire New AdhesiveNews
Researchers have taken inspiration from gecko toes to create a dry adhesive with stiff polycarbonate using a nanoimprinting technique to build web-like layers. The method is cost-effective, easy to perform and scalable. This development could someday make it easier to defy gravity.READ MORE
