Abstract
OBJECTIVE Angiogenesis facilitates tumor survival and promotes malignancy. The vascular endothelial growth factor (VEGF)/VEGF receptor (VEGFR) tyrosine kinase (TK) signaling pathway is a key factor mediating angiogenesis, suggesting that this pathway may be a target for diagnosis and therapy. In this study, we aimed to develop small molecule radioiodinated probes applicable for in vivo VEGFR imaging considering the versatility and usefulness of single-photon emission computed tomography (SPECT). METHODS We designed and synthesized four radioiodinated anthranilate compounds (6a-d) based on the structure of an anticancer drug targeting VEGFR-TK. The inhibitory potencies of corresponding cold compounds 4a-d and in vitro stability of compounds 6a-d were assessed by cellular proliferation inhibition assays and radio thin-layer chromatography after incubation in neutral solution. In vivo biodistributions were evaluated by determining radioactivity in tissues of interest after intravenous injection of test compounds in tumor-bearing mice. In vitro and in vivo blocking experiments using a selective VEGFR-TK inhibitor and SPECT/computed tomography (CT) imaging were performed in tumor-bearing mice. RESULTS The radioiodinated compounds 6a-d were obtained with more than 68.0% radiochemical yield and more than 95% radiochemical purity. Because compounds 4a-d showed high inhibitory potencies and compounds 6c and 6d showed high in vitro stability, 6c ([125I]m-NPAM) and 6d ([125I]p-NPAM) were further evaluated. Analysis of the in vivo biodistribution revealed a tumor to blood radioactivity ratio of greater than 4 at 24 h after [125I]p-NPAM administration. Accumulation of radioactivity in cultured tumor cells and tumor xenografts after [125I]p-NPAM administration was significantly blocked by inhibitor pretreatment. Tumors were clearly imaged at 24 h after [125I]p-NPAM injection with SPECT/CT in comparison to that in inhibitor-pretreated tumor-bearing mice. CONCLUSION [125I]p-NPAM may have potential applications as a lead compound for future development of a clinically usable VEGFR imaging probe for SPECT.

Exploring the Dual Inhibitory Activity of Novel Anthranilic Acid Derivatives towards α-Glucosidase and Glycogen Phosphorylase Antidiabetic Targets: Design, In Vitro Enzyme Assay, and Docking Studies. Molecules 2018; 23:molecules23061304.

Abstract
A few new anthranilate diamide derivatives, 3a–e, 5a–c and 7a–d, were designed, synthesized, and evaluated for their inhibitory activity against two interesting antidiabetic targets, α-glucosidase and glycogen phosphorylase enzymes. Different instrumental analytical tools were applied in identification and conformation of their structures like; 13C NMR, 1H NMR and elemental analysis. The screening of the novel compounds showed potent inhibitory activity with nanomolar concentration values. The most active compounds (5c) and (7b) showed the highest inhibitory activity against α-glucosidase and glycogen phosphorylase enzymes IC50 = 0.01247 ± 0.01 µM and IC50 = 0.01372 ± 0.03 µM, respectively. In addition, in vivo testing of the highly potent α-glucosidase inhibitor (7b) on rats with DTZ-induced diabetes was done and showed significant reduction of blood glucose levels compared to the reference drug. Furthermore, a molecular docking study was performed to help understand the binding interactions of the most active analogs with these two enzymes. The data obtained from the molecular modeling were correlated with those obtained from the biological screening. These data showed considerable antidiabetic activity for these newly synthesized compounds.

Abstract
Fatty acid amide hydrolase (FAAH) has a key role in the control of the cannabinoid signaling, through the hydrolysis of the endocannabinoids anandamide and in some tissues 2-arachidonoylglycerol. FAAH inhibition represents a promising strategy to activate the cannabinoid system, since it does not result in the psychotropic and peripheral side effects characterizing the agonists of the cannabinoid receptors. Here we present the discovery of a novel class of profen derivatives, the N-(heteroaryl)-2-(4-((2-(trifluoromethyl)pyridin-4-yl)amino)phenyl)propanamides, as FAAH inhibitors. Enzymatic assays showed potencies toward FAAH ranging from nanomolar to micromolar range, and the most compounds lack activity toward the two isoforms of cyclooxygenase. Extensive structure-activity studies and the definition of the binding mode for the lead compound of the series are also presented. Kinetic assays in rat and mouse FAAH on selected compounds of the series demonstrated that slight modifications of the chemical structure could influence the binding mode and give rise to competitive (TPA1) or non-competitive (TPA14) inhibition modes.

Abstract
The tumor suppressor p53 plays a key role in regulation of the cell cycle, apoptosis and senescence in response to various stresses. We screened a library of 7920 chemical compounds for the p53 activator and identified N-[2-(dimethylamino)ethyl]-2,3-dimethyl-4-oxo-4H-pyrido[1,2-a]thieno[2,3-d]pyrimidine-9-carboxamide (PTP), which significantly increased p53-mediated reporter activity in colorectal cancer cells. PTP was found to induce p53 protein and activated transcription of downstream genes, such as p21 and PUMA, in HCT116 cells, leading to growth delay, G1-phase cell cycle arrest, cell senescence and cell death. Proximity ligation assay revealed that PTP weakened the interaction between p53 and murine double minute 2 (MDM2) in situ, thereby inhibiting MDM2-mediated p53 degradation. Although DNA damage has been known to promote phosphorylation of p53 and MDM2, thereby preventing their interaction and stabilizing p53, PTP did not cause DNA damage or activate any DNA damage response signaling. Instead, phosphorylation of p53 was mediated by Erk1/2 MAP kinase. In addition, PTP induced acetylation of p53 at Lys382 in a p300-dependent manner, but sirtuin (SIRT)1 and histone deacetylase (HDAC)1, a well-known p53-regulating deacetylase, were not involved. In the present study, the novel anticancer agent PTP was shown to cause the accumulation of p53 by inducing multiple post-translational modifications, as well as cell cycle arrest, senescence and cell death.

Abstract
Small molecule HAT inhibitors are useful tools to unravel the role of histone acetyltransferases (HATs) in the cell and have relevance for oncology. We synthesized a series of N-acylanthranilic acids (11-16) and of N-acyl-5-hydroxyanthranilic acids (17-22) bearing C6, C8, C10, C12, C14, along with C16 acyl chain at the 2-amino position of anthranilic acid or 5-hydroxyanthranilic acid. Enzyme inhibition of these compounds was investigated, using in vitro PCAF HAT assays. All synthesized compounds (65-76%) showed similar inhibitory activity to anacardic acid (68%) at 100 μM. The cytotoxicity, against one normal cell line (HSF) and eight cancer cell lines (HT-29, HCT-116, MDA-231, A-549, Hep3B, Caski, HeLa and Caki), were evaluated by the SRB method.

Abstract
Our previous studies identified two 2-benzoylaminobenzoate derivatives 1, which potently inhibited superoxide (O(2)˙(-)) generation induced by formyl-L-methionyl-L-leucyl-L-phenylalanine (FMLP) in human neutrophils. In an attempt to improve their activities, a series of anthranilic acid derivatives were synthesized and their anti-inflammatory effects and underlying mechanisms were investigated in human neutrophils. Of these, compounds 17, 18, 46, 49, and 50 showed the most potent inhibitory effect on FMLP-induced release of O(2)˙(-) in human neutrophils with IC(50) values of 0.20, 0.16, 0.15, 0.06, and 0.29 μM, respectively. SAR analysis showed that the activities of most compounds were dependent on the ester chain length in the A ring. Conversely, a change in the linker between the A and B ring from amide to sulfonamide or N-methyl amide, as well as exchanges in the benzene rings (A or B rings) by isosteric replacements were unfavorable. Further studies indicated that inhibition of O(2)˙(-) production in human neutrophils by these anthranilic acids was associated with an elevation in cellular cAMP levels through the selective inhibition of phosphodiesterase 4. Compound 49 could be approved as a lead for the development of new drugs in the treatment of neutrophilic inflammatory diseases.

Abstract
The regioselectivity of coupling phenyl isocyanate to 3-(2-acylhydrazino)-3-aminopropenenitriles and ethyl 3-(2-acylhydrazino)-3-aminopropenoates as simple access to aminopyrazole derivatives, endowed with potential antitumoral activity, is reported. 3-(2-Acylhydrazino)-3-aminopropenenitriles react with phenyl isocyanate to afford 3-amino-3-(2-acylhydrazino)-2-phenylaminocarbonyl-2-propenenitriles. These key intermediates were cyclized into 3,5-diaminopyrazole-4-carboxamide derivatives. Preliminary results of poor antiproliferative activities of these compounds are also reported.

Abstract
The synthesis and anticancer activity of new compounds designed on the anthranilic acid scaffold are reported. The antiproliferative activity was assayed by the National Cancer Institute in established in vitro and in vivo anticancer experimental models. Structural variations based on the flufenamic acid motif afforded a series of (hetero)aryl esters of N-(2-(trifluoromethyl)pyridin-4-yl)anthranilic acid, which showed in vitro growth inhibitory properties against human tumor cell lines in nanomolar to low micromolar concentrations. The pyridinyl ester 25 exhibited very potent in vitro antiproliferative efficacy, with a chemosensitive profile showing a number of GI(50) values at concentrations lower than 10(-7) M in the full panel of human tumor cell lines. Compound 25 was also tested in vivo as a potential anticancer agent in the hollow fiber assay and in human tumor xenografts, showing moderate inhibitory properties. Analysis of biological activities and the COMPARE procedure was utilized to support putative biochemical mechanisms implicated with the antiproliferative activity.
