In the present work, two reaction-based generative models for molecular design are presented: Growing Optimizer and Linking Optimizer. These models are designed to emulate real-life chemical synthesis by sequentially selecting building blocks and simulating the reactions between them to form new compounds. By focusing on the feasibility of the generated molecules, Growing Optimizer and Linking Optimizer offer several advantages, including the ability to restrict chemistry to specific building blocks, reaction types, and synthesis pathways, a crucial requirement in drug design. Unlike text-based models, which construct molecules by iteratively forming a textual representation of the molecular structure, and graph-based models, which assemble molecules atom by atom or fragment by fragment, our approach incorporates a more comprehensive understanding of chemical knowledge, making it relevant for drug discovery projects. Comparative analysis with REINVENT 4, a state-of-the-art molecular generative model, shows that Growing Optimizer and Linking Optimizer are more likely to produce synthetically accessible molecules while reaching molecules of interest with the desired properties.

Since 2005, pupils and their guardians in Norwegian primary schools have had the right to be exempted from activities that they experience as problematic from their own outlook on life or that they experience as an exercise of someone else's outlook on life. In 2015, Bengt-Ove Andreassen called for a similar right in upper secondary school in an academic discussion with Njål Høstmælingen, in Prismet. With the new Education Act, which is valid from 01.08.2024, this will be a reality. In the light of human rights perspectives, and majority and minority perspectives, I discuss the changes in the right to exemption and the relationship to religion in the new Education Act. It is important to look at these changes to understand the framework that exists in Norwegian schools to safeguard the human rights of students and parents in various majority and minority contexts, with a new Education Act. Keywords: The rigth to be exempted, religion, religious education, Educational law

Abstract Generative models are frequently used for de novo design in drug discovery projects to propose new molecules. However, the question of whether or not the generated molecules can be synthesized is not systematically taken into account during generation, even though being able to synthesize the generated molecules is a fundamental requirement for such methods to be useful in practice. Methods have been developed to estimate molecule “synthesizability”, but, so far, there is no consensus on whether or not a molecule is synthesizable. In this paper we introduce the Retro-Score (RScore), which computes a synthetic feasibility score of molecules by performing a full retrosynthetic analysis through our data-driven synthetic planning software Spaya, and its dedicated API: Spaya-API (https://spaya.ai). We start by comparing several synthetic feasibility scores to a binary ground truth of synthetic feasibility as estimated by chemists on a bench of generated molecules, as a first experimental validation that the RScore is a reliable synthetic feasibility score. We then describe a pipeline to generate molecules that validate a list of targets while still being easy to synthesize. We further this idea by performing experiments comparing molecular generator outputs across a range of constraints and conditions. We show that the RScore can be learned by a Neural Network, which leads to a new score: RSPred. We demonstrate that using the RScore or RSPred as a constraint during molecular generation enables our molecular generators to produce more synthesizable solutions, with higher diversity. The open-source Python code containing all the scores and the experiments can be found on https://github.com/iktos/generation-under- synthetic-constraint.

Parkinson’s Disease (PD) is the second most prevalent neurodegenerative disease of the central nervous system, with an estimated 5,000,000 cases worldwide. Historically characterized by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta, PD pathology is now known to be widespread and to affect serotonin, cholinergic and norepinephrine neurons as well as nerve cells in the olfactory system, cerebral hemisphere, brain stem, spinal cord, and peripheral autonomic nervous system. PD pathology is characterized by the accumulation of misfolded α-synuclein, which is thought to play a critical role in the etiopathogenesis of the disease. Animal models of PD suggest that activation of the Abelson Tyrosine Kinase plays an essential role in the initiation and progression of α-synuclein pathology and neurodegeneration. These studies demonstrate that internalization of misfolded α-synuclein activates c-Abl which phosphorylates α-synuclein and promotes α-synuclein pathology within the affected neurons. Additionally, c-Abl inactivates parkin, disrupting mitochondrial quality control and biogenesis, promoting neurodegeneration. Post-mortem studies of PD patients demonstrate increased levels of tyrosine phosphorylated α-synuclein, consistent with the activation of c-Abl in human disease. Although the c-Abl inhibitor Nilotinib failed to demonstrate clinical benefit in two double-blind trials, novel c-Abl inhibitors have been developed that accumulate in the brain and may inhibit c-Abl at saturating levels. These novel inhibitors have demonstrated benefits in animal models of PD and have now entered clinical development. Here, we review the role of c-Abl in the neurodegenerative disease process and consider the translational potential of c-Abl inhibitors from model studies to disease-modifying therapies for Parkinson’s disease.

Skolans demokratiuppdrag innefattar att elever utvecklar ett kritiskt reflekterande förhållningssätt till texter. I denna artikel belyser vi utifrån ett critical literacy-perspektiv hur detta kritiska förhållningssätt kan förstås i relation till ett inslag i tibetanska skolor – den tibetanska argumentationstekniken. Tekniken är utvecklad inom en religiös och filosofisk kontext, men implementeras nu i sekulära skolor i ambition att stärka elevernas självförtroende och tänkande. Syftet med denna artikel är att fördjupa kunskapen om hur den tibetanska argumentationstekniken gestaltas i undervisning i exiltibetanska skolor i Dharamsala, Indien. Ett specifikt fokus riktas mot hur argumentationstekniken kan förstås utifrån ett perspektiv där utvecklandet av en kritisk reflexion ses som en nödvändig del av utbildningsuppdraget. Det empiriska materialet till artikeln består av observationer vid skolbesök och intervjuer med lärare. Våra resultat pekar på att lärarna, när de använder argumentationstekniken som en del av undervisningen, upplever att elever utvecklar sin språkförmåga och ämnesförståelse och dessutom stärker sitt självförtroende. Tillgången till verktyget verkar ge eleverna tillgång till språk och kunskaper som utvecklar deras förmåga till logiskt tänkande och att själva uttrycka sig, vilket i sin tur ger dem större makt att påverka sina framtida möjligheter. Resultaten pekar också på att argumentationstekniken lämpar sig särskilt väl för vissa ämnen och särskilda ämnesinnehåll.

<div> <div> <div> <p>Multi-Parameter Optimization (MPO) is a major challenge in New Chemical Entity (NCE) drug discovery projects, and the inability to identify molecules meeting all the criteria of lead optimization (LO) is an important cause of NCE project failure. Several ligand- and structure-based de novo design methods have been published over the past decades, some of which have proved useful multiobjective optimization. However, there is still need for improvement to better address the chemical feasibility of generated compounds as well as increasing the explored chemical space while tackling the MPO challenge. Recently, promising results have been reported for deep learning generative models applied to de novo molecular design, but until now, to our knowledge, no report has been made of the value of this new technology for addressing MPO in an actual drug discovery project. Our objective in this study was to evaluate the potential of a ligand-based de novo design technology using deep learning generative models to accelerate the discovery of an optimized lead compound meeting all in vitro late stage LO criteria. </p> </div> </div> </div>
