Which statement NOT a mechanism used by biologic DMARDs?

Explanation:
Biologic DMARDs achieve their effects by targeted immune modulation rather than broad metabolic blockade. Inhibiting pyrimidine synthesis is a metabolic mechanism seen with conventional DMARDs (for example, leflunomide) or antimetabolites, not with biologic agents. Biologic DMARDs work by blocking inflammatory pathways or cell interactions, such as inhibiting TNF, blocking IL-1/IL-6 signaling, or modulating T cell activation/co-stimulation. Because of that, the statement about inhibiting pyrimidine synthesis is not a mechanism used by biologic DMARDs.
