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.

Abstract
Urokinase-type plasminogen activator (uPA) plays an important role in the regulation of diverse physiologic and pathologic processes. Experimental research has shown that elevated uPA expression is associated with cancer progression, metastasis, and shortened survival in patients, whereas suppression of proteolytic activity of uPA leads to evident decrease of metastasis. Therefore, uPA has been considered as a promising molecular target for development of anticancer drugs. The present study sets out to develop the new selective uPA inhibitors using computer-aided structural based drug design methods. Investigation involves the following stages: computer modeling of the protein active site, development and validation of computer molecular modeling methods: docking (SOL program), postprocessing (DISCORE program), direct generalized docking (FLM program), and the application of the quantum chemical calculations (MOPAC package), search of uPA inhibitors among molecules from databases of ready-made compounds to find new uPA inhibitors, and design of new chemical structures and their optimization and experimental examination. On the basis of known uPA inhibitors and modeling results, 18 new compounds have been designed, calculated using programs mentioned above, synthesized, and tested in vitro. Eight of them display inhibitory activity and two of them display activity about 10 μM.

Abstract
Urokinase plasminogen activator (uPA) is an enzyme involved in cancer growth and metastasis. Therefore, the design of inhibitors of uPA is of high therapeutic value, and several chemical families have been explored, even if none has still emerged, emphasizing the need of a rationalized approach. This work represents a complete computational study of uPA complexed with five inhibitors, which present weak similarities. Molecular dynamics simulations in explicit solvent were conducted, and structural analyses, along with molecular mechanics (MM)/Poisson-Boltzmann surface area free energies estimations, yield precious structure-activity relationships of these inhibitors. Besides, we realized supplemental QM/MM computations that improved drastically the quality of our models providing original information on the hydrogen bonds and charge transfer effects, which are, most often, neglected in other studies. We suggest that these simulations and analyses could be reproduced for other systems involving protein/ligand molecular recognitions.

Abstract
Pancreatic cholesterol esterase (CEase), which is secreted from the exocrine pancreas, is a serine hydrolase that aids in the bile salt-dependent hydrolysis of dietary cholesteryl esters and contributes to the hydrolysis of triglycerides and phospholipids. Additional roles for CEase in intestinal micelle formation and in transport of free cholesterol to the enterocyte have been suggested. There also are studies that point to a pathological role(s) for CEase in the circulation where CEase accumulates in atherosclerotic lesions and triggers proliferation of smooth muscle cells. Thus, there is interest in CEase as a potential drug target. 4-Chloro-3-alkoxyisocoumarins are a class of haloenol lactones that inhibit serine hydrolases and serine proteases and have the potential to be suicide inhibitors. In the present study, we have developed 3-alkoxychloroisocoumarins that are potent inhibitors of CEase. These inhibitors were designed to have a saturated cycloalkane ring incorporated into a 3-alkoxy substituent. The size of the ring as well as the length of the tether holding the ring was found to be important contributors to binding to CEase. 4-Chloro-3-(4-cyclohexylbutoxy)isocoumarin and 4-chloro-3-(3-cyclopentylpropoxy)isocoumarin were demonstrated to be potent reversible inhibitors of CEase, with dissociation constants of 11nM and 19nM, respectively. The kinetic results are consistent with predictions from molecular modeling.

Abstract
Urokinase-type plasminogen activator (uPA), a highly restricted serine protease, plays an important role in the regulation of diverse physiologic and pathologic processes. Strong clinical and experimental evidence has shown that elevated uPA expression is associated with cancer progression, metastasis, and shortened survival in patients. uPA has been considered as a promising molecular target for development of anticancer drugs. Here, we report the identification of several new uPA inhibitors using a high-throughput screen from a chemical library. From these uPA inhibitors, molecular modeling and docking studies identified 4-oxazolidinone as a novel lead pharmacophore. Optimization of the 4-oxazolidinone pharmacophore resulted in a series of structurally modified compounds with improved potency and selectivity. One of the 4-oxazolidinone analogues, UK122, showed the highest inhibition of uPA activity. The IC(50) of UK122 in a cell-free indirect uPA assay is 0.2 micromol/L. This compound also showed no or little inhibition of other serine proteases such as thrombin, trypsin, plasmin, and the tissue-type plasminogen activator, indicating its high specificity against uPA. Moreover, UK122 showed little cytotoxicity against CFPAC-1 cells (IC(50) >100 micromol/L) but significantly inhibited the migration and invasion of this pancreatic cancer cell line. Our data show that UK122 could potentially be developed as a new anticancer agent that prevents the invasion and metastasis of pancreatic cancer.

Abstract
Platelet 12-lipoxygenase (P-12-LOX) is overexpressed in different types of cancers, including prostate cancer, and the level of expression is correlated with the grade of this cancer. Arachidonic acid is metabolized by 12-LOX to 12(S)-hydroxyeicosatetraenoic acid [12(S)-HETE], and this biologically active metabolite is involved in prostate cancer progression by modulating cell proliferation in multiple cancer-related pathways inducing angiogenesis and metastasis. Thus, inhibition of P-12-LOX can reduce these two processes. Several lipoxygenase inhibitors are known, including plant and mammalian lipoxygenases, but only a few of them are known inhibitors of P-12-LOX. Curcumin is one of these lipoxygenase inhibitors. Using a homology model of the three-dimensional structure of human P-12-LOX, we did computational docking of synthetic curcuminoids (curcumin derivatives) to identify inhibitors superior to curcumin. Docking of the known inhibitors curcumin and NDGA to P-12-LOX was used to optimize the docking protocol for the system in study. Over 75% of the compounds of interest were successfully docked into the active site of P-12-LOX, many of them sharing similar binding modes. Curcuminoids that did not dock into the active site did not inhibit P-12-LOX. From a set of the curcuminoids that were successfully docked and selected for testing, two were found to inhibit human lipoxygenase better than curcumin. False-positive curcuminoids showed high LogP (theoretical) values, indicating poor water solubility, a possible reason for lack of inhibitory activity or/and nonrealistic binding. Additionally, the curcuminoids inhibiting P-12-LOX were tested for their ability to reduce sprout formation of endothelial cells (in vitro model of angiogenesis). We found that only curcuminoids inhibiting human P-12-LOX and the known inhibitor NDGA reduced sprout formation. Only limited inhibition of sprout formation at approximately IC(50) concentrations has been seen. At IC(50), a substantial amount of 12-HETE can be produced by lipoxygenase, providing a stimulus for angiogenic sprouting of endothelial cells. Increasing the concentration of lipoxygenase inhibitors above IC(50), thus decreasing the concentration of 12(S)-HETE produced, greatly reduced sprout formation for all inhibitors tested. This universal event for all tested lipoxygenase inhibitors suggests that the inhibition of sprout formation was most likely due to the inhibition of human P-12-LOX but not other cancer-related pathways.
