In theoretical medicine, topological indices are defined to test the medicine and pharmacy characteristics, such as melting point, boiling point, toxicity and other biological activities. As basic molecular structures, hexagonal jagged-rectangle and distance-regular structure are widely appeared in medicine, pharmacy and biology engineering. In this paper, we study the chemical properties of hexagonal jagged-rectangle from the mathematical point of view. Several vertex distance-based indices are determined. Furthermore, the Wiener related indices of distance-regular structure are also considered.

Background: Small, soluble oligomers, rather than mature fibrils, are the major neurotoxic agents in Alzheimer's disease (AD). In the last few years, Aprile and co-workers designed and purified a single-domain antibody (sdAb), called DesAb-O, with high specificity for Aβ oligomeric conformers. Recently, Cascella and co-workers showed that DesAb-O can selectively detect synthetic Aβ oligomers both in vitro and in cultured cells, neutralizing their associated neuronal dysfunction.

Background: Focusing on novel AD treatments, the TREAT-AD centers offer an array of free research tools, shared via the AD Knowledge Portal in a Target Enablement Package (TEP). This abstract showcases the research conducted by the IUSM-Purdue TREAT-AD Center, specifically focusing on Targeting class-II PI3K's as a potential breakthrough in AD therapy. Endocytosis within the brain encompasses diverse pathways for internalizing extracellular cargoes and receptors into cells.

Background: Alzheimer disease (AD) is a progressive neurodegenerative disease that is accountable for the leading case of dementia in elder people. Before, only symptomatic treatments are available for AD. Since 2021, two anti-amyloid antibodies aducanumab and lecanemab have been approved by the US Food and Drug Administration.

Alzheimers Dement
December 2024
Indiana University School of Medicine, Indianapolis, IN, USA.
Background: The goal of the TREAT-AD Center is to enable drug discovery by developing assays and providing tool compounds for novel and emerging targets. The role of microglia in neuroinflammation has been implicated in the pathogenesis of Alzheimer's disease (AD). Genome-wide association studies, whole genome sequencing, and gene-expression network analyses comparing normal to AD brain have identified risk and protective variants in genes essential to microglial function.

Alzheimers Dement
December 2024
Institute of Science and Technology Austria (ISTA), Klosterneuburg, Austria.
Background: We identified small molecule tricyclic pyrone compound CP2 as a mild mitochondrial complex I (MCI) inhibitor that induces neuroprotection in multiple mouse models of AD. One of the major concerns while targeting mitochondria is the production of reactive oxygen species (ROS). CP2 consists of two diastereoisomers, D1 and D2, with distinct activity and toxicity profiles.
