Let D be an F-central division algebra. In this paper, we investigated the exponent of the group G(D)=D*/NrdD(D*)D ', where D* is the group of units of D, NrdD(D*) is the image of D* under the reduced norm map and D ' is the commutator subgroup of D*. We show that if exp (G(D))p-Phenylenediamine-2-Amino pyrimidine - Formaldehyde Terpolymer (P2APF) ligand's reactivity and drug suitability for malaria treatment: Insights from experimental and quantum calculations
