Some novel N5-sulfonylated 4 were synthesized via sulfonylation of 5-amino-1H-pyrazole derivative 1 with arylsulfonyl chlorides. On the other hand, N1-alkylated pyrazoles 7 and 10 were synthesized through alkylation of compound 1 with each of chloroacetamides and ethylchloroacetate under different conditions. Condensation of compounds 4 and 7 with different aromatic aldehydes furnished the corresponding arylidene derivatives. In spite of, condensation of 10 with aromatic aldehydes afforded the 2-(5-amino-2-aryl-1H-pyrazol-1-yl)acetic acid. The structure of the newly synthesized compounds was elucidated by elemental analyses and spectral data. Also, the suggested mechanisms for their formation were studied. Additionally, some selected new compounds were screened against antimicrobial activity. Compound 7c exhibited a higher activity against Candida albicans (inhibition zone diameter [IZD] = 31.3 ± 0.6 mm) than the standard antibiotic Nystatin (IZD = 21 ± 0.5 mm). Also, compound 7c showed minimum inhibitory concentration = 125 and 250 μg/mL against Klebsiella pneumonia and Staphylococcus aureus, respectively. Molecular docking study also was carried out for compound 7c.

A novel series of pyrazolo[1,5-a]pyrimidines were synthesized and proved by their spectral and elemental analysis, some elected of the newly synthesized compounds were examined for their cytotoxic activity employing MTT assay on two cancer cell lines (Breast and Hela cancers). Compounds 5, 7e and 7i showed the higher cytotoxicity against two cancer cell lines with (IC50 = 13.91 ± 1.4 and 22.37 ± 1.8 μM/L), (IC50 = 6.56 ± 0.5 and 8.72 ± 0.9 μM/L) and (IC50 = 4.17 ± 0.2 and 5.57 ± 0.4 μM/L) for two cancer cell lines breast and hela respectively, using doxorubicin as a reference drug. The most potent cytotoxic active compounds 5, 7e and 7i presented inhibitory activity against KDM (histone lysine demethylases) with IC50 = 4.05, 1.91 and 2.31 μM, respectively. The most potent KDM inhibitor 7e (IC50 = 1.91 μM) showed to cause cell cycle arrest at G2/M phase by 4 folds than control and induce total apoptotic effect by 10 folds more than control. In silico studies performed on the more potent cytotoxic active compounds 5, 7e and 7i included lipinisk's rule of five. Moreover, molecular docking study was utilized to explore the binding mode of the most active compounds to the target enzyme (PDB-ID: 5IVE). Also, some bioinformatics studies were carried out for compounds 7e and 7i using Swiss ADME (Swiss Institute of bioinformatics 2018).
