The synthesis of N-phenylpyrazolines 1-5 was performed by the cyclocondensation of phenylhydrazine and appropriate chalcones that have been synthesized from our previous work. All of the compounds were elucidated for their structure using GC-MS, FTIR, 1H, and 13C-NMR spectrometers. Their anticancer activity was evaluated against breast cancer cell line (T47D) and colorectal cancer cell line (WiDr). Compound 4 (4-(3-(4-chlorophenyl)-1-phenyl-4,5-dihydro-1H-pyrazol-5-yl)-2-methoxyphenol) was found to be the most potent compound with IC50 value of 13.11 µg/mL in T47D cell line and 3.29 µg/mL in WiDr cell line. Docking study was conducted to evaluate the interaction between all compounds and EGFR receptor on cancer cells. Among the tested compounds, compound 4 is the only compound that has interaction with MET769 residue through hydrogen bonding due to the presence of hydroxyl group on its structure. Our findings suggest that the synthesized N-phenylpyrazolines in this study have a promising anticancer activity.

Abstract Due to similar coordination chemistry of palladium and platinum, a large number of palladium compounds too have been investigated for their anticancer activity. In the present study we describe synthesis, characterization and anticancer activity of palladium complex [Bis(1,8-quinolato)palladium (II)], coded as NH3 against seven different cancer cell lines. NH3 is found to have higher antitumour activity than cisplatin against both parent ovarian A2780 cell line and cisplatin-resistant cell lines. Also, NH3 has the lowest IC50 value against HT-29 colorectal cancer cell line. The higher antitumour activity of NH3 is due to the presence of bulky 8-hydroxy-quinoline ligand thus reducing its reactivity. Proteomic study has identified significantly expressed proteins which have been validated through bioinformatics. NH3 has been found to be less toxic than cisplatin at 2.5 mg/kg and 5 mg/kg dosages on mice models. Binary combinations of NH3 with curcumin and epigallocatechin gallate (EGCG) have demonstrated dose and sequence dependent synergism in ovarian and colorectal cancer models. All of the preclinical studies indicate promising therapeutic potentiality of NH3 [Bis(1,8-quinolato)palladium (II) ] as an anticancer drug.

Aims and Objective: A series of novel phthalazine derivatives was synthesized with versatile, readily accessible electrophilic and nucleophilic reagents. The newly synthesized compounds were confirmed by the results of spectroscopic measurements. Hence, their potential clinical application investigated in particular for cancer treatment. Materials and Methods: The newly synthesized compounds were characterized by spectroscopic measurements and were tested for their in vitro anticancer activity by MTT assay against human liver cancer cell line. Docking study of all the synthesized compounds was performed within the active site of the enzyme VEGFR-2 (Vascular Endothelial Growth Factor Receptor-2). Results: The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 µM. Docking study showed that the synthesized compounds were fit in the VEGFR-2 active site almost at the same position of sorafenib and vatalanib with comparable docking scores (-15.20 to -8.92 was kcal/mol). Conclusion: we have synthesized a novel series of phthalazine derivatives and evaluated their potential anticancer activity against HEPG2 cell line. The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 µM. The SAR and docking studies pointed out that rigidification of the structure resulted in better activity and better binding within the active site of VEGFR-2 as in compounds 3, 5, 6 and 12. These results introduced new phthalazine derivatives having promising activity which could lead to the development of more potent anticancer agents.

A1 Receptor

Background: Adenosine receptor family, especially A1 type is-overexpressed in breast-derived tumor cells and the P53 gene is mutant in some of these cells while the casps gene is of wild type as well. The aim of this study was to evaluate the effect of the A1 receptor function on cell programmed death or proliferation, as well as the relationship between this receptor stimulation/inhibition and caspase 3 (casp3) expression in T47D cell line that has a mutant and non-functional P53 gene. Materials and Methods: The expression of casps3 was measured by real-time polymerase chain reaction and then flow cytometery and MTT assay were used to assess the apoptotic and proliferation cell rate after the treatment of T47D cells with specific agonist N6-cyclopentyladenosine (CPA) and antagonist 1,3-dipropyl-8-cyclopentylxanthine (DPCPX) of this receptor 24, 48, and 72 hours after treatment. Result: Our results indicated that DPCPX significantly induces apoptosis in T47D cells and the rate of survival cell after the reduction of this treatment, especially 72 hours after treatment. Finally, the expression of casp3 was up-regulated by DPCPX treatment, especially in 72 hours while CPA treatment had opposite results (P>0.05). Conclusion: In general, DPCPX could up-regulate casp3 gene expression and subsequently increase the apoptosis rate in T47D cells with casp3 expression without the P53 gene interference. Therefore, adenosine A1 receptor antagonists may be introduced as anti-cancer agents.

: A series of novel 1,3-thiazole derivatives (5a-i) with a modified phenothiazine moiety were synthesized and tested against cancer cell line MCF-7 for their cytotoxicity. Most of them (5a-i) were less cytotoxic or had no activity against MCF-7 cancer cell line. Material and Methods: The IC50 value of compound (4) was 33.84 μM. The compounds (5a-i) were also evaluated for antimicrobial activities, but no significant activity was observed. The antioxidant activity was conducted for target compounds (5a-i). The IC50 value of compound (5b) was 0.151mM. Results: The total amount of energy, ACE (atomic contact energy), energy of receptor (PDB: 5G5J), and ligand interaction of structure (4) were found to be 22.448 Kcal.mol-1 , -247.68, and -91.91 Kcal.mol-1, respectively. The structure (4) is well binded with the receptor because the values of binding energy, steric energy, and the number of hydrogen bondings are -91.91, 22.448 kcal.mol-1, and 2, respectively. It shows that structure (4) has good cytotoxicity with MCF-7 in vitro. Conclusion: The increasing of docking ability of structures (5a-i) with the receptor is presented in increasing order as (5f)>(5e)>(5g)>(5a)>(5b)>(5d)>(5c)>(5i)>(5h). The structure bearing substitution as thiosemicarbazone (4), nitrogen heterocyclic (5f), halogen (5e), and azide (5g) showed good cytotoxicity activity in vitro.

Background: Hydrazones, one of the important classes of organic molecules, are pharmaceutical agents comprising –CO-NH-N=CH- group in the structure therefore and exhibiting significant biological activity. Methods: 5-Chloro-N’-[(substituted)methylidene] pyrazine-2-carbohydrazide (3a-g) and their Pd(II) complexes (4a-h) were synthesized and investigated in vitro anticancer activity on A549, Caco2 cancer and normal 3T3 fibroblast cell lines, using the MTT assay. Results: Anticancer activity screening results revealed that some compounds showed remarkable cytotoxic effect. Among them, 5-chloro-N'-[(4-hydroxyphenyl)methylidene] pyrazine-2-carbohydrazide (3c) displayed higher cytotoxic activity against A549 cancer cell line than the reference drug cisplatin. Conclusion: Compound 3c showed high cytotoxic activity against A549 cancer cell line but it showed low cytotoxic effect against normal 3T3 fibroblast cell line. Antiproliferative and antimetastatic effects of 3c were determined by the real-time monitoring of cell proliferative system (RTCA DP). The cell proliferation, metastatic and invasive activities of A549 cells were decreased due to increased concentration of 3c.

Compound 2T (D-Phe-c(Cys-Tyr-DTrp- Dap-Tle-Cys)-Thr-NH2)had the highest antioxidant effect. The compound 4T (D-Phe-c(Cys-Tyr-D-Trp- Orn-Tle-Cys)-Thr-NH2) displayed antiproliferative effect on HeLa cells with IC50 30 µM. The peptide analog 3T (D-Phe-c(Cys-Tyr-D-Trp-Lys-Tle-Cys)-Thr-NH2) exerted the most pronounced inhibition on the cell vitality up to 53%, 56% and 65% resp. against MDA-MB-23, Hep G-2, HeLa in the higher tested concentration. Conclusion: The somatostatin analogs showed moderate influence on the vitality of different tumor cells and could be used in changing their pathology.
