Bispecific T-cell engager therapy for multiple myeloma.

With upfront use of triplet- and quadruplet-based regimens coupled with autologous stem cell transplant (ASCT) and maintenance lenalidomide, a high proportion of multiple myeloma (MM) patients are achieving deep and durable responses. Yet, myeloma invariably relapses, with refractoriness to one or more drugs at first relapse. This therapeutic gap has been partially filled by T-cell engager (TCE) therapies that have demonstrated remarkable response rates and prolonged remissions in heavily pretreated patients with MM, providing off-the-shelf immunotherapy options leading to the U.

Discovery of natural RORγt inhibitor using machine learning, virtual screening, and in vivo validation.

Introduction: Retinoic acid receptor-related orphan receptor gamma t (RORγt) is a crucial transcription factor regulating Th17 cells, which secrete the cytokine IL-17. RORγt inhibitors are regarded as a therapeutic modality in a wide range of autoimmunity including psoriasis.

Objectives: The objective of the study is to investigate novel RORγt inhibitors from natural products (NPs), combining machine learning (ML)-based virtual screening, chemotaxonomic analysis, molecular docking, and molecular dynamics simulations, and biological validation.

Taurine suppresses Aβ aggregation and attenuates Alzheimer's disease pathologies in 5XFAD mice and patient-derived cerebral organoids.

Alzheimer's disease (AD) is marked by amyloid-beta (Aβ) plaque buildup, tau hyperphosphorylation, neuroinflammation, neuronal loss, and impaired adult hippocampal neurogenesis (AHN). Taurine has shown protective effects in various cellular and animal models of AD, though the molecular mechanisms of free taurine and its effects in patient-derived models remain underexplored. This study evaluates taurine's therapeutic potential using integrated in silico, in vitro, in vivo, and ex vivo approaches.

Preparation of high-purity 1,3-distearoyl-2-oleoylglycerol (StOSt) via a two-step enzymatic interesterification combined with two-step solvent fractionation.

High-purity 1,3-distearoyl-2-oleoylglycerol (StOSt) was produced from high-oleic sunflower oil and ethyl stearate via a two-step enzymatic interesterification combined with a two-step solvent fractionation. Lipozyme RM IM (Rhizomucor miehei) was employed as a biocatalyst and the reaction was conducted in a packed-bed reactor. Molecular distillation was used to remove fatty acid ethyl esters from the reaction mixtures after enzymatic reactions.

Unlocking Ring-Opening Polymerization of Glycidyl Propargyl Ether via Lewis Pair Organocatalysts.

Alkyne groups provide exceptional versatility for functionalization in macromolecular systems. However, the controlled anionic ring-opening polymerization (AROP) of epoxide monomers bearing terminal alkynes remains challenging due to the lability of alkynes under strongly basic conditions. Herein, we present a controlled AROP of glycidyl propargyl ether enabled by Lewis pair organocatalysis, employing a phosphazene base and triethylborane.
