Abstract
Previous investigations on the incubation of phenstatin with rat and human microsomal fractions revealed the formation of nine main metabolites. The structures of eight of these metabolites have been now confirmed by synthesis and their biological properties have been reported. Eaton's reagent was utilized as a convenient condensing agent, allowing, among others, a simple multigram scale preparation of phenstatin. Synthesized metabolites and related compounds were evaluated for their antiproliferative activity in the NCI-60 cancer cell line panel, and for their effect on microtubule assembly. Metabolite 23 (2'-methoxyphenstatin) exhibited the most potent in vitro cytotoxic activity: inhibition of the growth of K-562, NCI-H322M, NCI-H522, KM12, M14, MDA-MB-435, NCI/ADR-RES, and HS 578T cell lines with GI(50) values <10nM. It also showed more significant tubulin polymerization inhibitory activity than parent phenstatin (3) (IC(50)=3.2 μM vs 15.0 μM) and induced G2/M arrest in murine leukemia DA1-3b cells. The identification of this active metabolite led to the design and synthesis of analogs with potent in vitro cytotoxicity and inhibition of microtubule assembly.

Abstract
A novel series of the biheterocycles-based compounds with core structure distinguished from combretastatin A-4 (1) and colchicine (5) have been synthesized and evaluated as potent anti-mitotic agents. Compound 1-(4'-Indolyl and 6'-quinolinyl)-4,5,6-trimethoxyindoles 13 and 19 showed substantial anti-proliferative activity against various human cancer cell lines, regardless to the tissue origin and the expression of multiple-drug resistance MDR1, with a mean IC(50) value of 38 and 24 nM respectively. Compound 13 (IC(50) = 1.7 μM) also exhibited similar anti-tubulin activities to 1 (IC(50) = 1.8 μM) and displayed strong binding property to the colchicine binding site on the microtubules. Computational modeling analysis revealed that the binding mechanism of compound 13 is similar to that of CA4.

Abstract
Microtubules are dynamic structures that play a crucial role in cellular division and are recognized as an important target for cancer therapy. In search of new compounds with strong antiproliferative activity and simple molecular structure, a new series of 2-amino-3-(3',4',5'-trimethoxybenzoyl)-5-(hetero)aryl ethynyl thiophene derivatives was prepared by the Sonogashira coupling reaction of the corresponding 5-bromothiophenes with several (hetero)aryl acetylenes. When these compounds were analyzed in vitro for their inhibition of cell proliferation, the 2- and 3-thiophenyl acetylene derivatives were the most powerful compounds, both of which exerted cytostatic effects at submicromolar concentrations. In contrast, the presence of a more flexible ethyl chain between the (hetero)aryl and the 5-position of the thiophene ring resulted in significant reduction in activity relative to the 5-(hetero)aryl acetylene substituted derivatives. The effects of a selected series of compounds on cell cycle progression correlated well with their strong antiproliferative activity and inhibition of tubulin polymerization. We found that the antiproliferative effects of the most active compounds were associated with increase of the proportion of cells in the G(2)/M and sub-G(1) phases of the cell cycle.

Abstract
The essential role of microtubules in mitosis makes them a major target of compounds useful for cancer therapy. In our search for potent antitumor agents, a novel series of 2-anilino-4-amino-5-aroylthiazoles was synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization, and cell cycle effects. SAR was elucidated with various substitutions on the phenylamino and aroyl moiety at the 2- and 5-positions, respectively, of the 4-aminothiazole skeleton. Tumor cell exposure to several of these compounds led to the arrest of HeLa cells in the G2/M phase of the cell cycle and induction of apoptosis.

Abstract
The biological importance of microtubules in mitosis and cell division makes them an interesting target for the development of anticancer agents. Small molecules such as benzo[b]furans are attractive as inhibitors of tubulin polymerization. Thus, a new class of inhibitors of tubulin polymerization based on the 2-(3',4',5'-trimethoxybenzoyl)-benzo[b]furan molecular skeleton, with electron-donating (Me, OMe or OH) or electron-withdrawing (F, Cl and Br) substituents on the benzene ring, was synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization and cell cycle effects. Adding a methyl group at the C-3 position resulted in increased activity. The most promising compound in this series was 2-(3',4',5'-trimethoxybenzoyl)-3-methyl-6-ethoxy-benzo[b]furan, which inhibits cancer cell growth at nanomolar concentrations and interacts strongly with tubulin by binding to the colchicine site.

Abstract
A robust p53 cell-based assay that exploits p53's function as a transcription factor was used to screen a small molecule library and identify bioactive small molecules with potential antitumor activity. Unexpectedly, the majority of the highest ranking hit compounds from this screen arrest cells in mitosis and most of them impair polymerization of tubulin in cells and in vitro. One of these novel compounds, JJ78:1, was subjected to structure-activity relationship studies and optimized leading to the identification of JJ78:12. This molecule is significantly more potent than the original hit JJ78:1, as it is active in cells at two-digit nanomolar concentrations and shows clear antitumor activity in a mouse xenograft model as a single agent. The effects of nocodazole, a well established tubulin poison, and JJ78:12 on p53 levels are remarkably similar, supporting that tubulin depolymerization is the main mechanism by which JJ78:12 treatment leads to p53 activation in cells. In summary, these results identify JJ78:12 as a potential cancer therapeutic, demonstrate that screening for activators of p53 in a cell-based assay is an effective way to identify inhibitors of mitosis progression and highlights p53's sensitivity to alterations during mitosis.

Abstract
1-Aroylindoline, 1-aroyl-1,2,3,4-tetrahydroquinoline, and 1-aroylindole derivatives were synthesized and evaluated for anticancer activity. The 4-amino and 4-hydroxy-1-aroylindoles 26 and 27 with IC 50 of 0.9 and 0.6 microM, respectively, exhibited antitubulin activity superior or comparable to that of colchicine and combretastatin A-4. They also showed antiproliferative activity with IC 50 of 0.3-5.4 nM in a set of human cancer cell lines.

Abstract
The 2-(3,4,5-trimethoxybenzoyl)-2-aminoindole nucleus was used as the fundamental structure for the synthesis of compounds modified with respect to positions C-4 to C-7 with different moieties (chloro, methyl, or methoxy). Additional structural variations concerned the indole nitrogen, which was alkylated with small alkyl groups such as methyl or ethyl. We have identified 1-methyl-2-(3,4,5-trimethoxybenzoyl)-3-amino-7-methoxyindole as a new highly potent antiproliferative agent that targets tubulin at the colchicine binding site and leads to apoptotic cell death.

Abstract
Novel phenstatin analogues with a 2-naphthyl moiety combined with either a 2,3,4- or a 3,4,5-trimethoxyphenyl ring have been synthesized, and their tubulin polymerization inhibiting and cytotoxic activities have been evaluated. The 2-naphthyl ring is a better replacement for the 3-hydroxy-4-methoxyphenyl ring in the phenstatin series than in the combretastatin series. For the naphthylphenstatins, the carbonyl is required, and the preferred orientation of the trimethoxyphenyl ring is the one found in combretastatins.

Abstract
We report the synthesis, antiproliferative activity, and SAR of novel heterocyclic ketones derived from carbazole sulfonamides. Most of the heterocyclic ketones showed strong cytotoxicities. (N-1-Methylindole-5-yl)-(3,4,5-trimethoxyphenyl)-methanone 8b gave the most potent cytotoxicity (9.2-26 nM) against seven human tumor cell lines. The mechanism of action of the heterocyclic ketones appears to involve targeting of tubulin, similar to that of CA-4 and different from the carbazole sulfonamides.

Abstract
The concise synthesis and structure-activity relationship (SAR) studies of 3-aroylindoles were carried out in an effort to improve the potency and solubility of anticancer drug candidate BPR0L075 (8) by exploring structure modifications through three regimens: substitution of the B ring, at the N1 position, and of the 3-carbonyl linker. The SAR information revealed that the methoxy group of the B ring could be replaced with an electron-donating group such as methyl (in compound 9) or N,N-dimethylamino (in compound 13) while retaining both strong cytotoxic and antitubulin activities. The introduction of amide (compounds 30-33) and carbamate (compounds 34-37) functionalities at the N1 position of 8 gave analogues with potent antiproliferative activities. The cytotoxic potency of 8 was improved by replacing the carbonyl group with sulfide (compound 41) or oxygen (compound 43), indicating that the carbonyl moiety is important but not essential. The N,N-dimethylamino derivative 13 not only displayed potent cytotoxicity and antitubulin activity, but also showed a markedly improved physicochemical profile relative to the parent compound.

Abstract
A series of boronic acid containing cis-stilbenes as potent inhibitors of tubulin polymerization was synthesized by the introduction of boronic acid as an acceptor-type functional group into the aromatic ring B of the combretastatin framework. High cell-growth inhibition was observed with boron compounds 13 c and 13 d, in which a hydroxy group on the aromatic ring B of combretastatin A-4 was replaced with boronic acid; IC50 values toward B-16 and 1-87 cell lines are 0.48-2.1 microM. Compounds 13 c and 13 d exhibited significant inhibitory activity toward tubulin polymerization (IC50=21-22 microM). The carboxylic acid derivative 17, which can be considered as a mimic of boronic acid 13 c, did not show significant inhibition of cell growth or tubulin polymerization. According to the FACScan analysis using Jurkat cells, apoptosis was induced after incubation for 8 h with 13 c at a concentration of >10(-8) M. Growth inhibitory experiments against a panel of 39 human cancer cell lines revealed 13 c to inhibit growth differently than combretastatin A-4; the correlation coefficient (r) between the two compounds was 0.553 in the COMPARE analysis.

Abstract
Benzophenones and its analogues are known for wide range of biological properties. Synthetic benzophenone analogue 2-benzoyl -phenoxy acetamide (BP-1) is proven to be potent antitumor and proapoptotic activity against EAT cells in-vivo. In the present report, we studied the antiangiogenic effect of BP-1 in EAT cells induced angiogenesis. Treatment with BP-1 in-vivo was demonstrated by the down regulation of the secretion of VEGF from EAT cells and inhibition of blood vessels formation indicating the potential angioinhibitory effect of BP-1 in EAT cells. HIF-1alpha protein, a transcription factor known to be key a regulator in hypoxia-induced angiogenesis was also down regulated by BP-1. Our findings indicated that, HIF-1alpha nuclear sequestration is repressed by BP-1 through inhibition of nuclear translocation. We postulate that diminished HIF-1alpha nuclear presence and activity in BP-1 treated EAT cells could be responsible for decreased VEGF expression and antiangiogenic effects.

Abstract
A series of substituted benzophenone analogues, (2-aroyl-4-methylphenoxy)acetamides 4a-e, have been synthesized via three-step synthesis sequence beginning with the 2-hydroxybenzophenones 1a-e in excellent yield. 1a-e on reaction with ethyl chloroacetate afford ethyl (2-aroyl-4-methylphenoxy)acetates 2a-e which on alkaline hydrolysis afforded (2-aroyl-4-methylphenoxy)ethanoic acid 3a-e. Compounds 3a-e on condensation with p-chloroaniline furnished benzophenone analogues 4a-e. In the present report, we investigated the anti-tumor and proapoptotic effect of benzophenones in Ehrlich ascites tumor (EAT) cells. Treatment of benzophenones in vivo resulted in inhibition of proliferation of EAT cells and ascites formation. Further, we demonstrate that the induction of apoptosis in EAT cells is mediated through activation of caspase-3. These results suggest a further possible clinical application of these synthetic compounds as potent anti-tumor and proapoptotic compounds.

Abstract
A new series of 2-amino-6-(2-alkyl or arylidenehydrazinyl)-4-(dialkylamino)pyrimidine-5-carbonitriles, 5-24, were synthesized in satisfactory overall yield, using 2-amino-4-(dialkylamino)-6-hydrazino-5-pyrimidinecarbonitriles 3, 4, as key intermediates, by applying classical synthetic methods to construct the hydrazone moiety at C-6 of the pyrimidine ring. Hydrazinopyrimidine derivatives 5-24 were evaluated for their in vitro anticancer activity toward cell lines of nine different types of human cancers. Some of the newly prepared compounds demonstrated inhibitory effects on the growth of a wide range of cancer cell lines generally at 10(-5)M level and in some cases at 10(-7)M concentrations.

Abstract
A new series of compounds, in which the 2-amino-4-methoxyphenyl ring of phenstatin analogue 5 was replaced with 2- or 3-amino-benzoheterocycles, was synthesized and evaluated for antiproliferative activity and inhibition of colchicine binding. The lack of activity of 3',4'-dimethoxy- and 4'-methoxy-benzoyl derivatives (8 and 9, respectively) indicates that the 3',4',5'-trimethoxybenzoyl moiety is critical for the activity. Two compounds, 7 and 11, displayed potent antiproliferative activity, with IC50 values ranging from 25 to 100 nM against a variety of cancer cell lines. Derivative 11 was more active than CA-4 as an inhibitor of tubulin polymerization. The results demonstrated that the antiproliferative activity was correlated with inhibition of tubulin polymerization.

Abstract
BPR0L075 is a novel synthetic compound discovered through research to identify new microtubule inhibitors. BPR0L075 inhibits tubulin polymerization through binding to the colchicine-binding site of tubulin. Cytotoxic activity of BPR0L075 in a variety of human tumor cell lines has been ascertained, with IC(50) values in single-digit nanomolar ranges. As determined by flow cytometry, human cervical carcinoma KB cells are arrested in G(2)-M phases in a time-dependent manner before cell death occurs. Terminal deoxynucleotidyl transferase-mediated nick end labeling assay indicates that cell death proceeds through an apoptotic pathway. Additional studies indicate that the effect of BPR0L075 on cell cycle arrest is associated with an increase in cyclin B1 levels and a mobility shift of Cdc2 and Cdc25C. The changes in Cdc2 and Cdc25C coincide with the appearance of phosphoepitopes recognized by a marker of mitosis, MPM-2. Furthermore, phosphorylated forms of Bcl-2, perturbed mitochondrial membrane potential, and activation of the caspase-3 cascade may be involved in BPR0L075-induced apoptosis. Notably, several KB-derived multidrug-resistant cell lines overexpressing P-gp170/MDR and MRP are resistant to vincristine, paclitaxel, and colchicine but not to BPR0L075. Moreover, BPR0L075 shows potent activity against the growth of xenograft tumors of the gastric carcinoma MKN-45, human cervical carcinoma KB, and KB-derived P-gp170/MDR-overexpressing KB-VIN10 cells at i.v. doses of 50 mg/kg in nude mice. These findings indicate BPR0L075 is a promising anticancer compound with antimitotic activity that has potential for management of various malignancies, particularly for patients with drug resistance.
