Background/objectives: The rapid spread of antimicrobial resistance (AMR) presents a critical threat to global health. Primary care plays a significant role in this crisis, with oral antibacterial drugs among the most prescribed medications. Antibacterial prescribing rates are often high and complicated in out-of-hours (OOH) services, including weekdays outside regular hours, weekends, and holidays, potentially exacerbating AMR.

Background: Recently, pyrido[2,3-] pyrimidine, triazolopyrimidine, thiazolopyrimidine, quinoline, and pyrazole derivatives have gained attention due to their diverse biological activities, including antimicrobial, antioxidant, antitubercular, antitumor, anti-inflammatory, and antiviral effects.

Objective: The synthesis of new heterocyclic compounds including 5-quinoline-pyrido[2,3-] pyrimidinone (-, , -), 6-quinoline-pyrido[2,3-]thiazolo[3,2-]pyrimidinone (, , -), 1,2,4-triazole-6-quinoline-pyrido[2,3-]thiazolo[3,2-]pyrimidinone (-), and pyrido[2,3-]thiazolo[3,2-]pyrimidine-ethyl-(pyridine)-9-thiaazabenzo[]azulenone () derivatives was performed with high yields while evaluating antimicrobial activities.

Methods: A new series of quinoline-pyrido[2,3-]thiazolo[3,2-]pyrimidine derivatives were prepared using a modern style and advanced technology, resulting in high yields of these new compounds.

Glycogen Synthase Kinase-3 beta (GSK-3β) is a crucial enzyme linked to various cellular processes, including neurodegeneration, autophagy, and diabetes. A structurally diverse set of 1293 molecules having GSK-3β modulatory activity has been used. Molecular docking and eXplainable Artificial Intelligence (XAI) have been used concomitantly.

The work being presented now combines severe gradient boosting with Shapley values, a thriving merger within the field of explainable artificial intelligence. We also use a genetic algorithm to analyse the HDAC1 inhibitory activity of a broad pool of 1274 molecules experimentally reported for HDAC1 inhibition. We conduct this analysis to ascertain the HDAC1 inhibitory activity of these molecules.

Neurodegeneration refers to the gradual loss of neurons and extensive changes in glial cells like tau inclusions in astrocytes and oligodendrocytes, α-synuclein inclusions in oligodendrocytes and SOD1 aggregates in astrocytes along with deterioration in the motor, cognition, learning, and behavior. Common neurodegenerative disorders are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), spinocerebellar ataxia (SCA), and supranuclear palsy. There is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them.
