Abstract:
There has been considerable interest in the development of novel compounds with anticonvulsant, antioxidant, antibacterial, and antifungal activities. The present study explores the antimicrobial activity of some new arylidene hydrazide derivatives and correlates the effect on the antimicrobial potency by varying the substituents on hydrazide part of the arylidine hydrazide. Hydrazones possessing an azomethine–NHN=CH- proton constitute an important class of compounds for new drug developments; therefore, a series of arylidene hydrazides were synthesized with various aromatic aldehydes/ketones.

Abstract:
Indandiones are a relatively new group of compounds presenting a wide range of biological activities. The synthesis of these compounds was performed via a Knoevenagel reaction between an aldehyde and 1,3-indandione and were obtained with a yield up to 54%. IR, 1H-Nucleic Magnetic Resonance (NMR), 13C-NMR, LC/MS ESI+ and elemental analysis were used for the confirmation of the structures of the novel derivatives. Lipophilicity values of compounds were calculated theoretically and experimentally by reversed chromatography method as values RM. The novel derivatives were studied through in vitro a

Abstract:
Steroids constitute a unique class of chemical compounds, playing an important role in physiopathological processes, and have high pharmacological interest. Additionally, steroids have been associated with a relatively low toxicity and high bioavailability. Nowadays, multiple steroidal derivatives are clinically available for the treatment of numerous diseases. Moreover, different structural modifications on their skeleton have been explored, aiming to develop compounds with new and improved pharmacological properties. Thus, steroidal arylidene derivatives emerged as a relevant example of thes
