Mechanochemically Driven Synthesis of Anticancer Cocrystals: A Case Study of Lenalidomide

Chemistry–Methods, Volume 6, Issue 5, May 2026.
The combination of crystal engineering and mechanochemical approaches is a powerful strategy for the rational screen and development of new solid forms of active pharmaceutical ingredients (API). New supramolecular patterns formed between an API and a coformer allow the adjustment of physicochemical properties of drugs.

Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

European Journal of Inorganic Chemistry, Volume 29, Issue 13, 1 May 2026.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Peptidic product derived from trypsin autolysis modulates insect digestive proteases and supports plant biochemical defense

Pest Management Science, Volume 82, Issue 5, Page 4632-4647, May 2026.
XXXX Abstract BACKGROUND Spodoptera frugiperda, commonly known as the fall armyworm, is a highly economically significant pest that affects various crops, resulting in substantial losses in productivity. Managing this pest primarily relies on chemical insecticides; however, the repeated development of resistance to these chemicals has rendered them ...

University Exams and Psychosocial Stress: Effects on Cortisol Rhythmicity in Students

Clinical Endocrinology, Volume 104, Issue 5, Page 436-442, May 2026.
ABSTRACT Background University exams are recognised as naturalistic stressors that may elicit psychosocial and physiological responses in students. This pilot study investigated the short‐ and long‐term effects of exam‐related stress on hypothalamic–pituitary–adrenal (HPA) axis activity, focusing on cortisol production and rhythmicity.
