White mold, caused by the necrotrophic fungus , is a challenging disease to common bean cultivation worldwide. In the current study, two non-proteinogenic amino acids (NPAAs), -aminobutyric acid (GABA) and -alanine, were suggested as innovative environmentally acceptable alternatives for more sustainable management of white mold disease. , GABA and -alanine individually demonstrated potent dose-dependent fungistatic activity and effectively impeded the radial growth and development of mycelium.

Phytohormones mainly affect plant development and trigger varied responses to biotic and abiotic stresses. The sensitivity of methods used to profile phytohormones is a vital factor that affects the results. We used an improved GC-MS-based method in the selective ion-monitoring (SIM) mode to study the phytohormone profiling in citrus tissues.

A new series of 4-alkyl/aryl-2-oxo-1-pyrazolyl-1,2-dihydropyridine-3-carbonitriles, pyrazolo[3,4-b]pyridine-5-carbonitriles and pyrido[2,3-d]pyrimidine-6-carbonitriles have been synthesized and tested for their anti-inflammatory and analgesic activities. Among the tested compounds, 3e and 8b exhibited comparable anti-inflammatory activity to the standard (indomethacin). Compounds 5, 7a, and 8b displayed potent analgesic activity.

Some new substituted quinoxaline and furo[2,3-b]quinoxaline derivatives have been synthesized and tested for their anti-inflammatory and analgesic activities and for their ulcerogenic potential. The pharmacological evaluation of selected synthesized compounds revealed that 5a was equipotent and compounds 3, 4b, 4e and 5b possessed strong anti-inflammatory activity in chronic inflammatory models compared with indometacin (CAS 53-86-1) as reference drug. In addition, compound 4a was the safest one and the others showed little ulcerogenic activity.
