Thienopyridines, a class of oral antiplatelet agents, permanently inhibit P2RY12 signaling, which is sufficient to block platelet activation. F2R, TBXA2R and P2RY1 couple to the Gq-PLC-IP3-Ca2+ pathway, inducing shape change and platelet aggregation.

Internal Rate of Return (IRR) Internal rate of return (IRR) is the interest rate at which the net present value of all the cash flows (both positive and negative) from a project or investment equal zero. Internal rate of return is used to evaluate the attractiveness of a project or investment. If the IRR of a new project exceeds a companyâs required rate of return, that project is desirable. If IRR falls below the required rate of return, the project should be rejected.
