“Our vision is to enable breakthroughs in the treatment of diseases with high unmet medical need by partnering our lead discovery engine with leaders in the pharmaceutical industry such as Pfizer.”Under the terms of the agreement, X-Chem is applying its discovery engine, which leverages a high diversity, proprietary DNA-encoded small molecule library to seek the identification of novel leads for the Pfizer programs. Microzide (Hydrochlorothiazide) with free prescription Pfizer has an exclusive option to license any compounds generated in the course of the collaboration. The financial terms of the agreement were not disclosed.
“The use of ultra-large and highly diverse DNA-encoded small molecule libraries has emerged as a novel technology with potential to generate leads for difficult targets of high importance,” said Tony Wood, Senior Vice President, Worldwide Medicinal Chemistry, Pfizer. “At Pfizer we are keen to explore new technologies that may help expand our pipeline of innovative medicines and are pleased to initiate this collaboration with X-Chem to access their innovative lead generation approach.”
“With the ongoing expansion of X-Chem’s library, informatics capabilities, and screening expertise, we continue to identify lead molecules to challenging, high value therapeutic targets,” said Rick Wagner, Ph.D., Chief Executive Officer of X-Chem. Minipress (Prazosin) without prescription “Our vision is to enable breakthroughs in the treatment of diseases with high unmet medical need by partnering our lead discovery engine with leaders in the pharmaceutical industry such as Pfizer.”
“Through a series of strategic research collaborations, and repeated success at reaching collaboration goals and licensing programs to our partners, X-Chem has demonstrated its ability to structure and execute partnerships that bring significant value to both parties,” said Diala Ezzeddine, Ph.D., Chief Business Officer of X-Chem.
About the X-Chem Drug Discovery Platform
Due to the size and diversity of the library, X-Chem has the potential to discover multiple series of novel, potent and selective lead compounds at an accelerated rate of success against a wide range of targets, including some that previously failed using conventional screening methods. Buy Droxia (Hydroxyurea) without prescription A number of proprietary innovations in library design, screening methodology and bioinformatics underlie the strong performance of the platform. A key advancement was a library synthesis process that enables addition of the DNA tag using chemical methods, as exemplified in the following publication by X-Chem scientists: Litovchick A, Clark MA, Keefe AD. Universal strategies for the DNA-encoding of libraries of small molecules using the chemical ligation of oligonucleotide tags. Artificial DNA: PNA & XNA; 5 (1) e27896 1 – 11 (2014). X-Chem’s approach to library design allows for additional chemical reactions to become useable in DNA-encoded library synthesis. Together, these developments have the potential to result in a much greater repertoire of diversity for small molecules, which cover a range of categories, including fragment molecules, small molecular weight heterocyclic compounds, and macrocyclic structures. Buy Actosplus Met with free Rx This diverse library, combined with a heightened ability to detect active molecules, has yielded a robust process that has been highly successful against targets categorized as difficult or intractable.
About DNA Encoding
The X-Chem drug discovery engine is based on a library generated by iterative combinatorial synthesis of small molecules tethered to DNA tags which record the synthetic history of the small molecule. Buy Vitamins online Every small molecule in the library has a unique DNA barcode attached to it. The library is screened as a mixture using affinity-based binding to a target of interest. Certain rare molecules in the library that bind to the target can be “fished out,” while the rest of the molecules wash away. DNA sequencing methods are then used to detect molecules that are enriched when bound to the target. Doctor Online Consultation The diverse nature of the library produces multiple families or clusters of related molecules that bind to the target, forming a basis for emergent structure-activity relationships. Structure-activity relationships are typically used by medicinal chemists to guide iterative chemical maturation of a lead molecule into a drug. Based on the synthetic history encoded in the DNA sequence information, molecules are then made without the DNA tag attached, and tested for activity in conventional assays.
