A computational procedure was performed on some indenopyrazole derivatives. Two important procedures in computational drug discovery, namely docking for modeling ligand-receptor interactions and quantitative structure activity relationships were employed. MIA-QSAR analysis of the studied derivatives produced a model with high predictability. The developed model was then used to evaluate the bioactivity of 54 proposed indenopyrazole derivatives. In order to confirm the obtained results through this ligand-based method, docking was performed on the selected compounds. An ADME-Tox evaluation was also carried out to search for more suitable compounds. Satisfactory bioactivities and ADME-Tox profiles for two of the compounds, namely 62 and S13, propose that further studies should be performed on such devoted chemical structures.

Lawsones and indenopyrazoles are the prevalent structural motifs and building blocks in pharmaceuticals and bioactive molecules, but their synthesis has always remained challenging as no comprehensive protocol has been outlined to date. Herein, a metal-free, ring-expansion reaction of indantrione with diazomethanes, generated in situ from the N-tosylhydrazones, has been developed for the synthesis of lawsone and indenopyrazole derivatives in acetonitrile and alcohol solvents, respectively. It provides these valuable lawsone and pyrazole skeletons in good yields and high levels of diastereoselectivity from simple and readily available starting materials.

Indenopyrazole is emerging as one of the most promising and privileged scaffold in medicinal chemistry. This scaffold have been investigated for the development of novel derivatives and hybrids with other moieties and substituents exhibiting a wide range of medicinal properties like antimycobacterial, antipsychotic, antihypertensive, cannabinoid receptor affinity, anti-tumor, antimicrobial, etc. Furthermore, indenopyrazoles function as inhibitors in various mechanistic pathways which has been well established based on its anticancer potential.

A series of novel indenopyrazole derivatives 2a-j and 3a-j were synthesized from the reaction of 1-(4-(hydroxy(1-oxo-1,3-dihydro-2 H-inden-2-ylidene)methyl)phenyl)-3-phenylurea derivatives 1a-j with hydrazine and phenylhydrazine, respectively. The obtained novel indenopyrazoles ( 2a-j and 3a-j) were evaluated for anticancer activity against HeLa and C6 cell lines. Antiproliferative activity was determined by the BrdU proliferation ELISA assay; 2a, 2b, 2d, 2h, and 3h were found to be the most active compounds.
