Abstract
Drug affinity and function depend on the different protonation species (present in the biological context) that generate different conformational ensembles with different structural features and, hence, different physico-chemical properties.
In the present review article these strongly interdependent structural features will be considered for their crucial role in ligand-based QSAR modeling and drug design by using quantum chemical electronic/reactivity descriptors and molecular shape description. Some selected and relevant examples illustrate the role of these molecular descriptors, computed on the bioactive protonation states and conformers, as determinant factors in mechanistic/causative QSAR analysis.
Keywords: Quantum chemical descriptors, molecular size-shape, causative QSAR.

Advances in the Molecular Pathogenesis of Inflammatory Bowel Disease.
This thematic issue will emphasize the recent breakthroughs in the mechanisms of Inflammatory bowel disease (IBD) pathogenesis and devotes some understanding of both Crohn’s and ulcerative colitis. It is expected to include studies about cellular and genetic aspects, which help to precipitate the disease, and the immune system-gut microbiome relations ...read more
Blood-based biomarkers in large-scale screening for neurodegenerative diseases
Disease biomarkers are necessary tools that can be employed in several clinical context of use (COU), ranging from the (early) diagnosis, prognosis, and prediction, to monitoring of disease state and/or drug efficacy. Regarding neurodegenerative diseases, in particular Alzheimer’s disease (AD), a battery of well-validated biomarkers are available, such as cerebrospinal ...read more
