Through the development and understanding of small molecules, our lab explores links between the regulation of drug targets and the system level properties of biological networks within cells and animals. Our goals are to create new tools to modulate and explore biomolecular function, with a long-term objective of developing innovative medicines for disease. Our work is highly interdisciplinary, employing methods from synthetic organic chemistry, X-ray crystallography, mass spectrometry, informatics, biochemistry and model organism genetics.
In one research area we are investigating one of the most frequently activated pathways in cancer biology: the Ras-Mitogen Activated Protein Kinase (MAPK) pathway. Oncogenic forms of Ras occur in over 20% of all cancers. These mutants have stifled direct pharmacological approaches and inhibitors for the direct effectors of Ras have shown limited or no efficacy in patients. We are exploring new targets or strategies to modulate the Ras pathway through the development of chemical tools. In particular, we are using target-based and systems pharmacology approaches to generate new classes of small molecule modulators for the Ras pathway.

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.
Dr. Dar has not yet completed reporting of Industry relationships.
Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).
Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.
Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
