Abstract
Drospirenone (DE) is a fourth-generation progesterone that has been widely used in oral contraceptives for women because of its safety and few side effects in terms of pharmacological activity. A new solvatomorph (crystal form C) of DE with dimethyl sulfoxide was identified and characterized for the first time through a thermogravimetry-mass spectrometry (TG-MS) coupling system. The thermodynamic property of the new solvatomorph of DE was different from those of most pharmaceutical solvatomorphs, and it was revealed via the skimmer-type interfaced TG-MS system and differential scanning calorimetry. This new solvatomorph and a polymorph of DE obtained without solvent (crystal form A) were well characterized by X-ray crystallography and vibrational spectroscopic analysis. Computational studies based on their single-crystal structures, such as Hirshfeld surface analyses, were used to determine the intermolecular interactions in the crystal network. The single-crystal structure of crystal form C of DE was determined and reported for the first time.

Abstract
The interaction of drospirenone (DP) with human serum albumin (HSA)/lysozyme (LYZ) was investigated using different optical techniques and molecular models. Results from the emission and time resolved fluorescence studies revealed that HSA/LYZ emission quenching with DP was initiated by static quenching mechanism. The LYZ-DP system was more easily influenced by temperature than the HSA-DP system. Displacement experiments demonstrated that the DP binding site was mainly located in site 1 of HSA. Based on the docking methods, DP was mainly bound in the active site hinge region where Trp-62 and Trp-63 are located. Conformation study showed that DP had different effects on the local conformation of HSA and LYZ molecules.
