structures were characterized by IR, 1H NMR, 13C NMR and HR-MS spectroscopic methods. The newly synthesized compounds were evaluated for their inhibitoryactivity against monoamine oxidase enzymes (MAO-A and MAO-B). Compounds 2a, 2k, 4a and 4i showed significant inhibitoryactivity against MAO-A, with IC50 value in the range of 0.084–0.207 µM compared to reference drug moclobemide (IC50 value = 6.061 µM)
A series of novel phenylurea containing 2‐benzoylindan‐1‐one derivatives 3a – 3j were synthesized from the reaction of phenylurea‐substituted acetophenones 1a – 1j with phthalaldehyde 2 under mild reaction conditions in good yields. All synthesized compounds were characterized by spectroscopic methods. The obtained compounds (3a – 3j) were evaluated for anticancer activity against HeLa and C6 cell
deaths today. Serious research for ideal chemotherapy continues today. In this context, newly synthesized molecules have an essential role in cancer treatment research. The effects of 5 diaryl ureaderivatives synthesized within the scope of this study on the HT-29 colon cancer cell line were investigated for the first time in the literature by in-silico and in-vitro methods. Among the five compounds
Compounds of Formula I are provided. In which the variables are as described herein. Such compounds may be used to modulate CB1 activity in vivo or in vitro, and are particularly useful in the treatment of conditions responsive to CB1 modulation in humans, domesticated companion animals and livestock animals, including appetite disorders, obesity and addictive disorders. Pharmaceutical compositions and methods for using them to treat such disorders are provided, as are methods for using such ligands for receptor localization studies and various in vitro assays.

An inherently challenging enantioselective direct reductive amination reaction under mild and operationally simple transfer hydrogenative conditions was developed using a rationally designed, chiral pyridine-derived half-sandwich iridium catalyst. The reaction was compatible with various functional groups and coordinative heterocycles.
