Abstract
Novel phthalazine derivatives were designed, synthesized and evaluated against Hep G2 and MCF-7 as VEGFR-2 inhibitors. In particular, compounds 2g and 4a were found to be the most potent derivatives among all the tested compounds against MCF-7 and Hep G2 cancer cell lines with IC50 values of 0.15 and 0.12 and 0.18 and 0.09 μM respectively. Moreover, compounds 3a, 3c, 5a and 5b displayed excellent anticancer activities against MCF-7 and Hep G2 cancer cell lines. The highly active derivatives 2g, 3a, 3c, 4a, 5a and 5b were evaluated for their inhibitory activities against VEGFR-2. The tested compounds displayed high to low inhibitory activities with IC50 values ranging from 0.148 to 0.892 μM. Among them, compounds 2g and 4a were found to be the most potent derivatives that inhibited VEGFR-2 with IC50 values of 0.148 and 0.196 μM respectively. Compounds 3a, 3c, 5a and 5b exhibited good activity with IC50 values of 0.375, 0.892, 0.548 and 0.331 μM respectively. Sorafenib was used as a reference drug in this study. Molecular modeling studies were carried out for all compounds against the VEGFR-2 active site. The data obtained from biological testing highly correlated with those obtained from molecular modeling studies. Moreover, MD simulation results indicated the stability of ligand-target interaction. Furthermore, our derivatives 2g and 4a showed a good in silico calculated ADMET profile.

Abstract
The parent 2-(4-benzyl-1-oxophthalazin-2(1H)-yl)-acetohydrazide (4) has twenty-nine compounds. The starting material for their corresponding mono, dipeptides and reactions with active methylene compounds were produced by chemoselective N-alkylation of 4-Benzyl-2H-phthalazin-1-one (2) with ethyl chloroacetate to afford (4-benzyl-1-oxo-1H-phthalazin-2-yl) methyl acetate (3). The ester 3 was hydrazinolyzed to give hydrazide 4, then azide 5 coupled with amino acid ester hydrochloride and/or amines to produce several monopeptides, then the methyl (2-(4-benzyl-1-oxophthalazin-2(1H)-yl) acetyl) glycinate (7a) was hydrazinolyzed to produce corresponding hydrazide 2-(4-benzyl-1-oxophthalazin-2(1H)-yl)-N-(2-hydrazineyl-2-oxo ethyl) acetamide (8a). The hydrazide 8a under azide coupling method was coupled with amino acid ester hydrochloride and/or amines to produce several dipeptides, and the hydrazide 8a was also condensed and/or cyclized with several carbonyl compounds. The cytotoxicity of the synthesized compounds was tested using MTT assay, as well as apoptosis-induction through EGFR inhibition. Compounds 11d, 12c and 12d exhibited potent cytotoxic activities with IC50 values of 0.92, 1.89 and 0.57 μM against MDA-MB-231 cells compared to Erlotinib (IC50 = 1.02 μM). Interestingly compound 12d exhibited promising potent EGFR inhibition with an IC50 value 21.4 nM compared to Erlotinib (IC50 = 80 nM). For apoptosis, compound 12d induced apoptosis in MDA-MB-231 cells by 64.4-fold (42.5% compared to 0.66 for the control); hence, this compound may serve as a potential target-oriented anti-breast cancer agent. These results agreed with the molecular docking studies that highlighted the binding disposition of compound 12d towards EGFR protein. Hence, compound 12d may serve as a potential and selective anti-breast cancer agent.

Abstract
In accordance with the significant impetus of the discovery of potent vascular endothelial growth factor receptor 2 (VEGFR-2) inhibitors, herein, we report the design, synthesis, and anticancer evaluation of 12 new N-substituted-4-phenylphthalazin-1-amine derivatives against HepG2, HCT-116, and MCF-7 cells as VEGFR-2 inhibitors. The results of the cytotoxicity investigation indicated that HCT-116 and MCF-7 were the most sensitive cell lines to the influence of the newly synthesized derivatives. In particular, compound 7a was found to be the most potent derivative among all the tested compounds against the three cancer cell lines, HepG2, HCT116, and MCF-7, with IC50 = 13.67 ± 1.2, 5.48 ± 0.4, and 7.34 ± 0.6 µM, respectively, which is nearly equipotent to that of sorafenib (IC50 = 9.18 ± 0.6, 5.47 ± 0.3, and 7.26 ± 0.3 µM, respectively). All synthesized derivatives, 4a,b-8a-c, were evaluated for their inhibitory activities against VEGFR-2. The tested compounds displayed high to low inhibitory activity, with IC50 values ranging from 0.14 ± 0.02 to 9.54 ± 0.85 µM. Among them, compound 7a was found to be the most potent derivative that inhibited VEGFR-2 at an IC50 value of 0.14 ± 0.02 µM, which is nearly 72% of that of the sorafenib IC50 value (0.10 ± 0.02 µM). Compounds 7b, 8c, 8b, and 8a exhibited very good activity with IC50 values of 0.18 ± 0.02, 0.21 ± 0.03, 0.24 ± 0.02, and 0.35 ± 0.04 µM, respectively. Molecular modeling studies were carried out for all compounds against the VEGFR-2 active site. The data obtained from biological testing highly correlated with that obtained from molecular modeling studies. However, these modifications led to new phthalazine derivatives with higher VEGFR-2 inhibitory activities than vatalanib and which are nearly equipotent to sorafenib.

Abstract
A series of anilinophthalazine derivatives 4a-j was initially synthesized and tested for its VEGFR-2 inhibitory activity where it showed promising activity (IC50 = 0.636-5.76 μM). Molecular docking studies guidance was used to improve the binding affinity for series 4a-j towards VEGFR-2 active site. This improvement was achieved by increasing the hydrophobic interaction with the hydrophobic back pocket of the VEGFR-2 active site lined with the hydrophobic side chains of Ile888, Leu889, Ile892, Val898, Val899, Leu1019 and Ile1044. Increasing the hydrophobic interaction was accomplished by extending the anilinophthalazine scaffold with a substituted phenyl moiety through an uriedo linker which should give this extension the flexibility required to accommodate itself deeply into the hydrophobic back pocket. As planned, the designed uriedo-anilinophthalazines 7a-i showed superior binding affinity than their anilinophthalazine parents (IC50 = 0.083-0.473 μM). In particular, compounds 7g-i showed IC50 of 0.086, 0.083 and 0.086 μM, respectively, which are better than that of the reference drug sorafenib (IC50 = 0.09 μM).

Abstract
In our endeavor towards the development of effective VEGFR-2 inhibitors, three novel series of phthalazine derivatives based on 1-piperazinyl-4-arylphthalazine scaffold were synthesized. All the newly prepared phthalazines 16a-k, 18a-e and 21a-g were evaluated in vitro for their inhibitory activity against VEGFR-2. In particular, compounds 16k and 21d potently inhibited VEGFR-2 at sub-micromolar IC50 values 0.35 ± 0.03 and 0.40 ± 0.04 μM, respectively. Moreover, seventeen selected compounds 16c-e, 16g, 16h, 16j, 16k, 18c-e and 21a-g were evaluated for their in vitro anticancer activity according to US-NCI protocol, where compounds 16k and 21d proved to be the most potent anticancer agents. While, compound 16k exhibited potent broad spectrum anticancer activity with full panel GI50 (MG-MID) value of 3.62 μM, compound 21d showed high selectivity toward leukemia and prostate cancer subpanels [subpanel GI50 (MG-MID) 3.51 and 5.15 μM, respectively]. Molecular docking of compounds16k and 21d into VEGFR-2 active site was performed to explore their potential binding mode.

Abstract
The sensitivity limitations for magnetic resonance imaging of organic molecules have recently been addressed by hyperpolarization methods, which prepare excess nuclear spin polarization. This approach can increase sensitivity by orders of magnitude, but the enhanced signal relaxes away in tens of seconds, even in favorable cases. Here we show theoretically that singlet states between strongly coupled spins in molecules can be used to store and retrieve population in very-long-lived disconnected eigenstates, as long as the coupling between the spins substantially exceeds both the couplings to other spins and the resonance frequency difference between them. Experimentally, 2,3-carbon-13-labeled diacetyl has a disconnected eigenstate that can store population for minutes and is read out by hydration to make the two spins inequivalent.

Abstract
Novel derivatives of 1,2,4-triazoles are described as potent ATP-competitive inhibitors of vascular endothelial growth factor receptors I and II (VEGFR-1/2). A number of compounds display VEGFR-2 inhibitory activity comparable to that of Vatalanib and Vandetanib in both homogenous time-resolved fluorescence enzymatic and cellular assays. Several active molecules feature high intrinsic permeability (>30 x 10(-5) cm/min) across Caco-2 cell monolayer.

Abstract
We have developed a series of novel potent 1-(2-(pyridin-4-yl)ethyl)-1H-azole-5-carboxamides active against kinases VEGFR-2 and -1. Both specific and dual ATP-competitive inhibitors of VEGFR-2 were identified. Kinase selectivity could be controlled by varying the 5-carboxamide substituent at the azole ring. The most specific molecules displayed >10-fold selectivity for VEGFR-2 over VEGFR-1. Compound activities in vitro and in cell-based assays (IC(50)<100 nM) were similar to those of reported clinical and development candidates, including PTK787 (Vatalanib(trade)) and ZD6474 (Vandetanib(trade mark)). High permeability of active compounds across the Caco-2 cell monolayer (>40 x 10(-5)cm/min) is indicative of their potential for intestinal absorption upon oral administration.
