A series of 4-anilinoquinazoline–triazole–AZT hybrids were designed and synthesized as anticancer agents. Their cytotoxic potential has been evaluated by means of a micro-dilution assay against three human cancer cell lines (KB, epidermoid carcinoma; HepG2, hepatoma carcinoma; SK-Lu-1, non-small lung cancer). The biological results revealed that compounds 4b and 6d showed good anticancer activities against KB, HepG2, and Lu cell lines (IC50 values ranging from 9 μM to 100 μM). Especially, compounds 4b and 6d exhibited up to 3-fold more potent than reference drugs erlotinib hydrochloride and AZT in term of anti-lung cancer activity.

: Tetrahydroquinoline and isoquinoline scaffolds are important class heterocyclic compounds, which is implied for the development of new drugs and diagnostic for therapeutic function. Naturally occurring as well as synthetic tetrahydroquinolines/isoquinolines possess many different biological activities and have been testified as remarkable cytotoxic and potency in human cancer cell lines. Tetrahydroquinoline/isoquinolines based compounds displayed a key role in the development of anticancer drugs or lead molecules and acting through various mechanisms such as cell proliferation, apoptosis, DNA fragmentation, inhibition of tubulin polymerization, induced cell cycle arrest, interruption of cell migration, and modulation. The number of tetrahydroquinoline/isoquinoline derivatives has been reported as potent anticancer agents. Due to promising anticancer activities and wide-ranging properties of these molecules, we have compiled the literature for the synthesis and anticancer properties of various tetrahydroquinolines and isoquinolines. We have reported the synthesis of potent tetrahydroquinoline/isoquinoline molecules of the last 10 years with their anticancer properties in various cancer cell lines and stated their half-maximal inhibitory concentration (IC50). In addition, we also considered the discussion of molecular docking and structural activity relationship wherever provided to understand the possible mode of activity a target involved and structural feature responsible for the better activity, so the reader can directly find the detail for designing new anticancer agents.

Three series of fused pyrrolophenanthroline derivatives were designed as analogues of phenstatin and synthesized in two steps starting with 1,7-phenanthroline, 4,7-phenanthroline and 1,10-phenanthroline, respectively. Two (Compounds 8a and 11c) of the four compounds tested against a panel of sixty human cancer cell lines of the National Cancer Institute (NCI) exhibited significant growth inhibition activity on several cell lines. Compound 11c showed a broad spectrum in terms of antiproliferative efficacy with GI50 values in the range of 0.296 to 250 μM. Molecular docking studies indicated that Compounds 8a and 11c are accommodated in the colchicine binding site of tubulin in two different ways.

A linear strategy was adopted in synthesizing the novel amine derivatives 7(a-h) of 5-[5- (chloromethyl)-1, 3, 4-oxadiazol-2-yl]-2-(4-fluorophenyl)-pyridine (6) and screened these compounds for in vitro anticancer activity against three human cancer cell lines (HeLa,Caco-2 and HepG2). The synthesised novel compounds were characterized by 1H NMR, MS and 13C NMR spectroscopic evidences. Microwave irradiation of compound (5) in presence of chloroacetyl chloride and phosphoryl oxychloride yielded the dehydrated cyclized key intermediate 5-[5-(chloromethyl)-1,3,4-oxadiazol-2-yl]-2-(4-fluorophenyl)-pyridine which upon treatment with various primary or secondary amines (a-h) resulted into the corresponding amine derivatives. The IC50 values of the final compounds were compared with that of 5-fluorouracil (5-FU) taken as the standard. Compounds 7a and 7d were found to be highly cytotoxic against HepG2 cell lines with IC50 values of 2.6 ?M (IC50 = 34.0 ± 0.5 ?M) and 5.8 ?M (IC50 = 112 ± 1.4 ?M) respectively. The compound (7f) alone was found to have high cytotoxicity against Caco-2 cell lines with IC50 value of 2.3 ?M (IC50 = 87 ± 2.6 ?M).Dhaka Univ. J. Pharm. Sci. 16(1): 11-19, 2017 (June)

Background: Cancer exerts a huge strain on the health system. The emerging resistance to the current chemotherapies demands the continuous development of new anticancer agents with lower cost, higher efficacy, and greater specificity. Objective: Development of selective small molecules targeted anticancer agents Methods: The behavior of benzoxazinone 2 towards nitrogen nucleophiles such as hydrazine hydrate, formamide, ethanolamine, aromatic amines, and thiosemcarbazide was described. The behavior of the amino quinazolinone 3 towards carbon electrophiles and P2S5 was also investigated. The antiproliferative activity of 17 new benzoxazinone derivatives was examined against the growth of three human cancer cell lines; liver HepG2, breast MCF-7, and colon HCT-29, in addition to the normal human fibroblasts WI-38 and the selectivity index was calculated. The possible molecular pathways such as the cell cycle and apoptosis were investigated. Results: Derivatives 3, 7, 8, 10, 13, and 15 had a significant (less than 10 µM) antiproliferative activity against the three cancer cell lines investigated. Derivative 7 showed the best antiproliferative profile comparable to that of doxorubicin. The selectivity index for all the effective derivatives ranged from ~5-12 folds indicating high selectivity against the cancer cells. Derivative 15 caused ~ 7-fold and 8-fold inductions in the expression of p53 and caspase3, respectively. It also caused a ~ 60% reduction in the expression of both topoisomerase II (topoII) and cyclin-dependent kinase 1 (cdk1). Derivatives 3, 7, and 8 had a similar profile; ~ 6-8-fold increases in the expression of p53 and caspase3 but these compounds were devoid of any significant effect on the expression of topoII and cdk1. Derivatives 10 and 13 were also similar and resulted in a ~6-fold elevation in the expression of caspase3, and more than 60% downregulation in the expression of topoII. The results of the gene expression of topoII and caspase 3 were confirmed by the measurement of the topoII concentration and caspase3 activity in the HepG2 cells. Conclusion: Six derivatives exerted their antiproliferative activity by arresting the cell cycle (decreasing cdk1), preventing the DNA duplication (downregulating topo II), and by inducing apoptosis (inducing p53 and caspase3). One common feature in all the six active derivatives is the presence of free amino group. These compounds have merit for further investigations.

A series of novel structurally simple analogues based on nitidine was designed and synthesized in search of potent anticancer agents. The antitumor activity against human cancer cell lines (HepG2, A549, NCI-H460, and CNE1) was performed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay in vitro. The results showed that some of them had good anticancer activities, especially derivatives with a [(dimethylamino)ethyl]amino side chain in the C-6 position. Planar conjugated compounds 15a, 15b, and 15c, with IC50 values of 1.20 μM, 1.87 μM, and 1.19 μM against CNE1 cells, respectively, were more active than nitidine chloride. Compound 15b and compound 15c with IC50 values of 1.19 μM and 1.37 μM against HepG2 cells and A549 cells demonstrated superior activities to nitidine. Besides, compound 5e which had a phenanthridinone core displayed extraordinary cytotoxicity against all test cells, particularly against CNE1 cells with the IC50 value of 1.13 μM.

Abstract In the current paper, we describe the design, synthesis and antiproliferative screening of novel chloroquine derivatives with a quinoline core linked to a hydroxy or halogen amine through a flexible aminobutyl chain and urea spacer. Synthetic pathway leading to chloroquine urea derivatives 4-10 includes two crucial steps: i) synthesis of chloroquine benzotriazolide 3 and ii) formation of urea derivatives through the reaction of compound 3 with the corresponding amine. Testing of antiproliferative activity against four human cancer cell lines revealed that chloroquine urea derivatives 9 and 10 with aromatic moieties show activity at micromolar concentrations. Therefore, these molecules represent interesting lead compounds that might provide an insight into the design of new anticancer agents.

A series of 6- and 8-cinnamoylchromen-2-one and dihydropyranochromen-2-one derivatives were synthesized and their antiproliferative activities were evaluated against three human cancer cell lines, i.e., ovarian adenocarcinoma (SK-OV-3), leukemia (CCRF-CEM), and breast carcinoma (MCF-7). In general, 8-cinnamoylchromen-2-one derivatives were found to have higher antiproliferative activity against the cancer cells when compared with 6-cinnamoyl analogues. Among all of the hybrid chromen-2-one − chalcone/flavanone compounds, a 7-hydroxy-8-cinnamoylchromen-2-one derivative 35 was found to be consistently active against all the cancer cell lines and inhibited the cell proliferation of SK-OV-3, CCRF-CEM, and MCF-7 by 63%, 50%, and 43%, respectively, at a concentration of 50 μmol/L after 72 h of incubation. This compound also exhibited the highest Src kinase inhibition (IC50 = 14.5 μmol/L). Structure−activity relationship studies provided insights for designing the next generation of chromen-2-one − chalcone hybrid prototypes and the development of new leads as anticancer agents and (or) Src kinase inhibitors.

In western Africa ethnomedicine, Lannea barteri Oliv. (Anacardiaceae) is believed to have activity against gastrointestinal, neurological and endocrine diseases. Previous studies on this plant have revealed antimicrobial, anticholinestrase, anticonvulsant, antioxidant and anti-inflammatory activities. However, the anticancer potential of L. barteri has not been studied to date. The aim of this study was to evaluate the anticancer potential of hot and cold extracts and silica gel column chromatographic fractions of L. barteri leaf and stem bark. The extracts and fractions were tested for anticancer activity by using the crystal violet cell proliferation assay on four adherent human carcinoma cell lines—5637 (bladder), KYSE 70 (oesophagus), SiSo (cervical) and HepG2 (hepatic). The inhibitory concentration (IC50) of fractions IH, 1I, 2E and 2F were: 3.75 ± 1.33, 3.88 ± 2.15, 0.53 ± 0.41, and 0.42 ± 0.45 µg/mL against KYSE 70 and 1.04 ± 0.94, 2.69 ± 1.17, 2.38 ± 3.64, 2.17 ± 1.92 µg/mL against SiSo cell lines respectively. Fraction 2E showed weak apoptotic activity at double the IC50 and some sign of cell cycle arrest in the G2/M phase. Thus, phytoconstituents of L. barteri leaf and stem bark can inhibit the proliferation of cancer cell lines indicating the presence of possible anticancer agents in this plant.
