Abstract
A series of some new tetrahydroindolocarbazole derivatives has been synthesized. The structure of the synthesized compounds has been confirmed by different spectroscopic techniques such as IR, NMR, elemental analysis and mass spectrometry. The target compounds were evaluated for their antitumor activity against breast cancer cell line MCF-7, their GI% and their LC50 have been determined. Six of the synthesized compounds exhibited GI% values against MCF-7 cell lines exceeding 70% ranging from 71.9 to 85.0% in addition that compound 11 expressed GI% values of 99.9% and considered the most active derivatives among the synthesized ones. Compound 11 showed a remarkable decrease of u PA level to 3.5 ng/ml compared to DOX. Compound 5, 11 and 15 showed significant decrease in expression of MTAP and CDKN2A, in addition to a remarkable decrease in DNA damage comet assay method. Molecular modeling studies were performed to interpretate the behavior of active ligands as uPA inhibitors.

Abstract
Tetrahydroindolocarbazoles (THICZs) with versatile substituents, have been designed, synthesized, structure characterized, then investigated for their in-vitro anticancer screening, urokinase inhibition (uPA) evaluated, DNA-damage determination was further explored. Compounds 5, 8, 10 and 17 displayed the most promising antitumor activities against the breast cancer cell line as compared to the standard drug, doxorubicin with IC50 = 5.24 ± 0.37, 4.00 ± 0.52, 7.20 ± 0.90 and 9.60 ± 1.10 µg/ml (versus 3.30 ± 0.48 µg/ml for doxorubicin). Compounds 5, 8, 10 and 17 represents the most significant uPA inhibitors of our study with IC50 of 3.80, 2.70. 4.75, 10.80 (ng/ml) respectively. The expression levels of CDKN2A gene were decreased in 8, 10 and 17 cell lines as compared to those in positive control samples. Cell lines treated with 5, 8, 10 and 17 clearly observed a high score of damaged DNA cells. A deeper examination revealed that our hetroaromatics showed an extensive hydrogen bonding interactions that is required in the S pocket which is important for activity Arg 217, Gly 219, Gly 216, Lys 143 and Ser 190. So we present THICZs as promising uPA inhibitors expected as significant promise for further development as anti-invasiveness drugs.
