Abstract
The regioselective addition of sulfur and amine nucleophiles to a -CBr3 unit and nitromethyl moiety in a molecule with the installation of a five-diverse bond structure to novel isothiazole-5(2H)-thione is demonstrated. Umpolung of the nitromethyl group leads to a novel scaffold with selective C-N bond formation. Consequently, differentiating reactive centers by sulfur and amine nucleophiles has been proposed to create unique S-N bonds in conjunction with the dithioate (S═C-S-) moiety. This protocol allows for exploration of the -CBr3 moiety as a synthetic equivalent of the dithioate (S═C-S-) unit during the reaction.

Abstract
The microtubule is composed of αβ-tubulin heterodimers and is an attractive target for the
design of anticancer drugs. Over the years, various compounds have been developed and their effect on
tubulin polymerization has been studied. Despite great efforts to make an effective drug, no drug has
been introduced which inhibit colchicine binding site. In the current work, a series of pyrimidine derivatives
were designed and synthesized. Furthermore, their cytotoxic activities were evaluated and molecular
docking studies were performed. Twenty compounds of pyrimidine were synthesized in 2 different
groups. In the first group, 4,6-diaryl pyrimidine was connected to the third aryl group via thiomethylene
spacer. In the second group, this linker was substituted by S-CH2-triazole moiety. The cytotoxic
activity of these compounds was evaluated against 4 different cell lines (HT-29, MCF-7, T47D,
NIH3T3). Compounds 6d, 6m, 6p showed potent cytotoxic activity against MCF7 cancerous cell lines.
Between these compounds, compound 6p did not show cytotoxic activity against NIH- 3T3 (normal
cell) cell line. Docking studies show that these compounds occupy colchicine binding site in tubulin
protein and probably their anticancer mechanism is inhibition of tubulin polymerization. Altogether,
with respect to obtained results, it is attractive and beneficial to further investigation on pyrimidine
scaffold as antimitotic agents. Attention to the selectivity index of 6p on MCF7 cell line could be valuable
in design new chemical agents for the treatment of breast cancer.

Twelve compounds of pyrimidine were synthesized in 3 different groups. In the first group, 4,6-diaryl pyrimidine was connected to the third aryl group via thio-methylene spacer. In the second group, this linker was substituted by sulfoxide-methylene moiety and in the third group sulfone-methylene group was used as spacer. RESULTS The cytotoxic activity of these compounds were evaluated against 3 different cancerous cell lines (HT-29, MCF-7, T47D) as well as normal cell line (NIH3T3). Compounds in group 2 showed the best cytotoxicity and compound 7D: showed the most potent cytotoxic activity against all cell lines. Molecular modelling studies revealed that compound 7D: could strongly bind to the colchicine binding site of tubulin. CONCLUSION Altogether, with respect to obtained results, it is attractive and beneficial to further investigation on pyrimidine scaffold as antimitotic agents.

Abstract
OBJECTIVE Several anti-tubulin agents were introduced for the cancer treatment so far. Despite successes in the treatment of cancer, these agents cause toxic side effects, including peripheral neuropathy. Comparing anti-tubulin agents, indibulin seemed to cause minimal peripheral neuropathy, but its poor aqueous solubility and other potential clinical problems have led to its remaining in a preclinical stage. METHODS Herein, indibulin analogues were synthesized and evaluated for their in vitro anti-cancer activity using MTT assay (on the MCF-7, T47-D, MDA-MB231 and NIH-3T3 cell lines), annexin V/PI staining assay, cell cycle analysis, anti-tubulin assay and caspase 3/7 activation assay. RESULTS One of the compounds, 4a, showed good anti-proliferative activity against MCF-7 cells (IC50: 7.5 μM) and low toxicity on a normal cell line (IC50 > 100 μM). All of the tested compounds showed lower cytotoxicity on normal cell line in comparison to reference compound, indibulin. In the annexin V/PI staining assay, induction of apoptosis in the MCF-7 cell line was observed. Cell cycle analysis illustrated an increasing proportion of cells in the sub-G-1 phase, consistent with an increasing proportion of apoptotic cells. No increase in G2/M cells was observed, consistent with the absence of anti-tubulin activity. A caspase 3/7 assay protocol showed that apoptosis induction by more potent compounds was due to activation of caspase 3. CONCLUSION Newly synthesized compounds exerted acceptable anticancer activity and further investigation of current scaffold would be beneficial.

Abstract
BACKGROUND During last recent years number of anti-tubulin agents were introduced for treatment of diverse kind of cancer. Despite of their potential in treatment of cancer, drug resistance and adverse toxicity such as peripheral neuropathy are some of the negative criteria of anti-tubulin agents. METHODS Twenty seven quinazoline derivatives were synthesized using a multicomponent reaction. The cytotoxicity of compounds 1-27 was tested in SRB assays employing five different human tumor cell lines. Effect of two of active compounds on tubulin polymerization was also checked using a commercially available assay kit. Molecular modelling studies were also performed using autodock tools software. RESULTS SRB assays showed that compounds 2, 9, 16 and 26, being highly cytotoxic with IC50 values ranging between 2.1 and 14.3µM. The possible mode of action of compounds, 2, 9, 16 and 26, and the taxol binding site of the protein tubulin, an important goal for antimitotic drugs, was also studied by molecular docking, which showed reasonable interactions with tubulin active site, followed by investigation of the effects of compounds 9 and 16 on the polymerization of tubulin. The results showed the tested compounds to be highly active as inducers of tubulin polymerization. CONCLUSION Altogether, with respect to obtained results, it is attractive and beneficial to further investigation on quinazoline scaffold as antimitotic agents.

Abstract
Cancer is one of the major causes of mortality all around the world. Globally, nearly 1 in 6
deaths is due to cancer. Researchers are trying to synthesize new anticancer agents. Previous studies
demonstrated that some pyrazole derivatives could be considered as potential anticancer agents. Herein,
ten novel derivatives of 1,5-diarylpyrazole were synthesized in four step reactions and cytotoxic activity
was investigated by MTT cell viability assay. All of the compounds were characterized by 1H
NMR and 13C NMR and their purity was confirmed by elemental analysis. The cytotoxicity was determined
against three cancerous cell lines (HT-29, U87MG and MDA-MB 468) and AGO1522 as a
normal cell line. Compound 5a showed the best cytotoxic activity on cancerous cell lines in comparison
to paclitaxel. Annexin V/ PI staining assay also showed that compounds 5a and 5i would lead to
significant apoptosis induction in MDA-MB 486 cell line.

Abstract
Background:
Cancer is an important cause of human death worldwide. During the last
decades, many anticancer agents with anti-tubulin mechanism have been synthesized or extracted
from nature and some of them also entered clinical use. Indibulin is one of the most potent tubulin
polymerization inhibitors with minimal peripheral neuropathy, which is a big problem by some of
the antimitotic agents such as taxanes and vinka alkaloids. With respect to this giant benefit, herein
we decided to design and synthesize novel indibulin related compounds and investigate their
anticancer activity against HT-29, Caco-2 and T47-D cancerous cell lines as well as NIH-T3T as
normal cell line.
Objective:
The aim of this study was to synthesize new anti-cancer agents and evaluates their cytotoxic
activity on diverse cancerous and normal cell lines.
Method:
Target compounds were synthesized in multistep reaction and cytotoxic activity was
investigated by MTT cell viability assay.
Results:
Herein, nine novel target compounds were synthesized in moderate to good yield. Some
of the compounds exerted good cytotoxic activity against cancerous cell lines. Annexin V/PI staining
showed that compound 4g could induce apoptosis and necrosis in HT-29 cell line.
Conclusion:
It is valuable to do further investigation on compound 4g which showed the highest
activity against HT-29 and Caco-2 (IC50 values are 6.9 and 7 &µM respectively). Also, synthesis of
new derivatives of current synthesized compounds is suggested.

Abstract
BACKGROUND During recent years, a number of anti-tubulin agents were introduced for treatment of diverse types of cancer. Despite their potential in the treatment of cancer, drug resistance and adverse toxicity, such as peripheral neuropathy, are some of the negative effects of anti-tubulin agents. Among anti-tubulin agents, indibulin was found to cause minimal peripheral neuropathy. Thus far, however, indibulin has not entered clinical usage, caused in part by its poor aqueous solubility and other developmental problems in preclinical evaluation. OBJECTIVES With respect to need for finding potent and safe anticancer agents, in our current research work, we synthesized several indibulin-related diarylpyrrole derivatives and investigated their anti-cancer activity. METHODS Cell cultur studies were perfomred using the MTT cell viability assay on the breast cancer cell lines MCF-7, T47-D, and MDA-MB231 and also NIH-3 T3 cells as representative of a normal cell line. The activity of some of the synthesized compounds for tubulin interaction was studied using colchicine binding and tubulin polymerization assays. The annexin V-FITC/PI method and flow cytometric analysis were used for studying apoptosis induction and cell cycle distribution. RESULTS AND CONCLUSION Two of the synthesized compounds, 4f and 4 g, showed high activity on the MDA-MB231 cell line (IC50 = 11.82 and 13.33 μM, (respectively) and low toxicity on the normal fibroblast cells (IC50 > 100 μM). All of the tested compounds were more potent on T47-D cancer cells and less toxic on NIH-3 T3 normal cells in comparison to reference compound, indibulin. The tubulin polymerization inhibition assay and [3H]colchicine binding assay showed that the main mechanism of cell death by the potent synthesized compounds was not related to an interaction with tubulin. In the annexin V/PI staining assay, the induction of apoptosis in the MCF-7 and MDA-MB231 cell lines was observed. Cell cycle analysis illustrated an increased percentage of sub-G-1 cells in the MDA-MB231 cell line as a further indication of cell death through induction of apoptosis.

Abstract
Combretastatin A-4 (CA-4) (1) is a plant-derived anticancer agent binding to the tubulin colchicine site. Polyunsaturated fatty acids (PUFAs) are readily taken up by cancer cells and have been used to improve cell targeting. In the present study, four CA-4-PUFA conjugates were synthesized by coupling combretastatin A-4 (1) with several polyunsaturated fatty acids. The conjugates (2a-d) were characterized using spectroscopic methods. Their cytotoxicity was evaluated against human breast cancer cells (MCF-7), and the inhibition of tubulin polymerization was determined in vitro. All conjugates influenced tubulin polymerization, with the arachidonic acid conjugate (2c) displaying cytotoxicity similar in potency to the natural product CA-4 (1).

Abstract
AbstractIndibulin is one of the most potent tubulin polymerization inhibitors with minimal peripheral neuropathy. The design and synthesis of new indibulin analogs were carried out in order to investigate their anti-cancer activity. The target compounds 4a–i were synthesized in multistep reactions starting with the related indole derivatives. Compound 4f shows the highest cytotoxic activity on HT-29 and Caco-2 cell lines with the respective half maximal inhibitory concentration (IC50) values of 5.1 μm and 7.3 μm. In the case of the T47-D cell line, compound 4c exerts the best cytotoxic activity with an IC50 value of 11.5 μm. In the cell cycle analysis on HT-29 cells, compound 4f at 5.1 μm showed an increase in the percentage of cells in the sub-G1 phase. Altogether, nine target compounds were synthesized and characterized by infrared spectroscopy (IR), proton nuclear magnetic resonance (1H NMR), carbon-13 nuclear magnetic resonance (13C NMR), mass spectrometry (MS) and elemental analysis. Some of the compounds show good cytotoxic activity against cancerous cell lines.

Abstract
The dynamic and crucial role of tubulin in different cellular functions rendered it a promising target in anticancer drug development. Combretastatin A-4 (CA-4), an inhibitor of tubulin polymerization isolated from natural sources, is a lead molecule with significant cytotoxicity against tumour cells. Owing to its non polar nature it exhibits low solubility in natural biological fluids, thereby prompting the development of new CA-4 based derivatives. The modification of this lead molecule was mostly carried out by keeping the crucial cis-orientation of the double bond intact, along with a trimethoxyphenyl aromatic ring, by employing different approaches. The issue of solubility was also addressed by the development of water soluble prodrugs of CA-4. The present review highlights the investigations into the parallel development of both new CA-4 based derivatives and prodrugs in the past few years.

Abstract
Combretastatin A-4, first isolated from the African willow tree Combretum caffrum, is a tubulin polymerization inhibitor in medicine. It was first postulated as a potential fungicide targeting fungal tubulin for plant disease control in this study. Combretastatin A-4 and its derivatives were synthesized and tested against Rhizoctonia solani and Pyricularia oryzae. Several compounds have EC50 values similar to or better than that of isoprothiolane, which is widely used for rice disease control. Structure-activity relationship study indicated the the cis configuration and hydroxyl group in combretastatin A-4 are crucial to the antifungal effect. Molecular modeling indicated the binding sites of combretastatin A-4 and carbendazim on fungal tubulin are totally different. The bioactivity of combretastatin A-4 and its derivatives against carbendazim-resistant strains was demonstrated in this study. The results provide a new approach for fungicide discovery and fungicide resistance management.
