Abstract
A simple chiroptical solution for the absolute stereochemical determination for asymmetric phosphorus V stereocenters is presented. Strong coordination of the phosphorus oxide with the Zn-metallo center of the racemic host Zn-MAPOL 2 leads to an induced axial chirality of the host, yielding a strong ECCD signal. A mnemonic is proposed to correlate the asymmetry of the guest molecule with the observed ECCD signal. A simple chiroptical solution for the absolute stereochemical determination for asymmetric phosphorus V stereocenters is presented.![]()

Abstract
Cyclophosphamide is presently the most frequently used drug for antineoplastic chemotherapy. It has shown a great response in the treatment of human malignancies including leukemia, lymphoma, germ cell tumours, medulloblastomas, and carcinomas of the breast, lung, and cervix. Cyclophosphamide is also one of the most important immunosuppressive agents. This study investigates the quantum-chemical electronic properties of cyclophosphamide, as well as some of its metabolites, which are computed using ab-initio and DFT calculations. The interaction energy calculations between water molecules and the cyclophosphamide show how, in the solid state, the presence of water of crystallisation will make cyclophosphamide more stable over time. Atomic charges, dipole moment, frontier molecular orbitals, electrostatic potential isosurface, geometric parameters, and proton affinity on every nitrogen site enable the characterisation of the electronic properties and clearly illustrate the reactive sites that could be associated with this biologically important class of molecules.

Abstract
Pharmacokinetic and pharmacodynamic properties of drugs and their ultimate therapeutic effects are often significantly influenced by interactions between the geometry of host receptors, host enzymes, and the three-dimensional structure of drugs. Drug molecules that are mirror images of each other are chiral stereoisomers, and such chiral isomer compounds are commonly used as therapeutic agents by rheumatologists either as racemates (mixtures of chiral isomers) or as pure stereoisomers. Understanding and using such stereoisomeric drugs may lead to lower risks of drug toxicity, better therapeutic indices, and newer approaches for the treatment of articular disorders. A review of the properties of these special isomers is presented, and their therapeutic advantages are discussed.

Abstract
Quantum chemical calculations were performed on the formation of intermediates with trigonal bipyramidal (TBP) configurations in the hydrolysis of adenosine 3',5'-monophosphate (cAMP) with phosphodiesterases and the activation of protein kinases by cAMP. The results show that in the reaction sequence concerning the hydrolysis of cAMP with phosphodiesterase the TBP intermediate must possess an equatorial-apical cyclic phosphate ring with the 3'-oxygen atom in the apical position. This could be an additional reason for the sensitivity of the 3' position in cAMP towards modifications in comparison with the 5' position. According to the calculations, a mechanistic model is presented for the enzymatic hydrolysis of cAMP with the involvement of a covalently bonded enzyme-nucleotide intermediate. Also a model is offered for the activation of protein kinase by cAMP. The activation of protein kinase is assumed to proceed via diequatorial-ring-positioned TBP intermediates resulting in the formation of a covalent bond between cAMP and the protein kinase with retention of the cyclic phosphate ring. It seems likely that the enzyme-nucleotide intermediate enforces a conformational change in the enzyme, which causes the dissociation of the regulatory and catalytic subunit of the protein kinase, necessary for a physiological response.
