A series of eight quinoline-thiazole hybrid-bearing diazenylsulfonamides, 4a-4h, were synthesized and characterized by UV-Vis, FT/IR, 1H NMR and lC-MS. These compounds were formed when two prepared intermediate precursors of Schiff-base compounds, (E)-N-((2-chloroquinolin-3-yl)methylene)-4phenylthiazol-2-amine (3a) and (E)-N-((2-chloroquinolin-3-yl)methylene)-4-chlorophenylthiazol-2-amine (3b) were converted to the corresponding diazenyl compounds 4a-4h by treating and coupling with the individual diazonium salts of sulfa-drugs. The results of in vitro cytotoxic activity of the synthesized compounds in two cancer cell lines MCF 7 (human breast cancer cell line) and K562 (myelogenousleukemia cell line) have shown the IC50 values as given: 4b against MCF 7 19.52 and against K562 20.55µM; 4d against MCF 7 15.96 and against K562 13.05µM. Moreover, the compound 4-(((Z)-(2-chloroquinolin-3yl)(4-phenylthiazol-2-ylimino)methyl)diazenyl)benzenesulfonic acid (4d) induced maximum percentage of apoptosis. Furthermore, the in vitro antioxidant activity study revealed that among all the synthesized compounds, compound 4d has an excellent radical scavenging effect. Molecular docking was additionally performed to investigate the binding affinity of H-bonding interaction of synthesized compounds with a targeted enzyme and to compare it with the anticancer drugs, dasatinib, bosutinib and dacarbazine.

Background: Cancer is a major cause of death worldwide, despite many different drugs available to treat the disease. This high mortality rate is largely due to the complexity of the disease, which results from several genetic and epigenetic changes. Therefore, researchers are constantly searching for novel drugs that can target different and multiple aspects of cancer. Experimental: After a screening, we selected one novel molecule, out of ninety-four triazole derivatives, that strongly affects the viability and proliferation of the human breast cancer cell line MCF-7, with minimal effects on non-cancer cells. The drug, named DAN94, induced a dose-dependent decrease in MCF-7 cells viability, with an IC50 of 3.2 ± 0.2 µM. Additionally, DAN94 interfered with mitochondria metabolism promoting reactive oxygen species production, triggering apoptosis and arresting the cancer cells on G1/G0 phase of cell cycle, inhibiting cell proliferation. These effects are not observed when the drug was tested in the non-cancer cell line MCF10A. Using a mouse model with xenograft tumor implants, the drug preventing tumor growth presented no toxicity for the animal and without altering biochemical markers of hepatic function. Results and Conclusion: The novel drug DAN94 is selective for cancer cells, targeting the mitochondrial metabolism, which culminates in the cancer cell death. In the end, DAN94 has been shown to be a promising drug for controlling breast cancer with minimal undesirable effects.

: A series of novel 1,3-thiazole derivatives (5a-i) with a modified phenothiazine moiety were synthesized and tested against cancer cell line MCF-7 for their cytotoxicity. Most of them (5a-i) were less cytotoxic or had no activity against MCF-7 cancer cell line. Material and Methods: The IC50 value of compound (4) was 33.84 μM. The compounds (5a-i) were also evaluated for antimicrobial activities, but no significant activity was observed. The antioxidant activity was conducted for target compounds (5a-i). The IC50 value of compound (5b) was 0.151mM. Results: The total amount of energy, ACE (atomic contact energy), energy of receptor (PDB: 5G5J), and ligand interaction of structure (4) were found to be 22.448 Kcal.mol-1 , -247.68, and -91.91 Kcal.mol-1, respectively. The structure (4) is well binded with the receptor because the values of binding energy, steric energy, and the number of hydrogen bondings are -91.91, 22.448 kcal.mol-1, and 2, respectively. It shows that structure (4) has good cytotoxicity with MCF-7 in vitro. Conclusion: The increasing of docking ability of structures (5a-i) with the receptor is presented in increasing order as (5f)>(5e)>(5g)>(5a)>(5b)>(5d)>(5c)>(5i)>(5h). The structure bearing substitution as thiosemicarbazone (4), nitrogen heterocyclic (5f), halogen (5e), and azide (5g) showed good cytotoxicity activity in vitro.

Recent drug discovery efforts are highly focused towards identification, design, and synthesis of small molecules as anticancer agents. With this aim, we recently designed and synthesized novel compounds with high efficacy and specificity for the treatment of breast tumors. Based on the obtained results, we constructed a Volsurf+ (VS+) model using a dataset of 59 compounds able to predict the in vitro antitumor activity against MCF-7 cancer cell line for new derivatives. In the present paper, in order to further verify the robustness of this model, we report the results of the projection of more than 150 known molecules and 9 newly synthesized compounds. We predict their activity versus MCF-7 cell line and experimentally verify the in silico results for some promising chosen molecules in two human breast cell lines, MCF-7 and MDA-MB-231.

Tumor-associated macrophages often correlate with tumor progression, and therapies targeting immune cells in tumors have emerged as promising treatments. To select effective therapies, we established an in vitro 3D multicellular spheroid model including cancer cells, fibroblasts, and monocytes. We analyzed monocyte infiltration and differentiation in spheroids generated from fibroblasts and either of the cancer cell lines MCF-7, HT-29, PANC-1, or MIA PaCa-2. Monocytes rapidly infiltrated spheroids and differentiated into mature macrophages with diverse phenotypes in a cancer cell line-dependent manner. MIA PaCa-2 spheroids polarized infiltrating monocytes to M2-like macrophages with high CD206 and CD14 expression, whereas monocytes polarized by MCF-7 spheroids displayed an M1-like phenotype. Monocytes in HT-29 and PANC-1 primarily obtained an M2-like phenotype but also showed upregulation of M1 markers. Analysis of the secretion of 43 soluble factors demonstrated that the cytokine profile between spheroid cultures differed considerably depending on the cancer cell line. Secretion of most of the cytokines increased upon the addition of monocytes resulting in a more inflammatory and pro-tumorigenic environment. These multicellular spheroids can be used to recapitulate the tumor microenvironment and the phenotype of tumor-associated macrophages in vitro and provide more realistic 3D cancer models allowing the in vitro screening of immunotherapeutic compounds.

Breast cancer is the subsequent foremost reason of cancer death in a woman and ranks as the primary foremost reason of death in India. In its conduct, several measures and recommendation are considered. Homoeopathic medicines are one of the part of a corresponding, and another medicine is utilized for the treatment of cancer. The main purpose of the investigation is to evaluate the anticancer action of homoeopathic arrangements of Asterias rubens  on the basis of the similia principle. We directed an in vitro study using MTT assay to control the result of ultra diluted homoeopathic preparation in contradiction of two human breast glandular cancer cell lines(MCF-7 and MDA-MD- 231), frequently used for the breast cancer treatment, by testing the feasibility of breast cancer (MCF-7 and MDA-MD-231) cell line, with various attenuations of Asterias rubens  at 24 hrs. Multiple comparisons between tested reagents at different concentrations confirmed the significance of the said results. At a dilution of 1:25 6CH and 30CH potency shown superior activity on MCF-7 and no such significant changes on MDA-MD-231 at any dilutions As it fails to offer estrogen receptor(ER) Also progesterone receptor (PR) expression, and also HER2 (human epidermal development variable receptor2) so continuously a triple-negative breast cancer it will be a hostility manifestation for breast cancer with restricted medicine choices. However, further potency needs to be tested. These preliminary significant results warrant further in vitro and in vivo studies to estimate the possible of Asterias rubens  a medicine to treat breast cancer.

ABSTRACT We report here that the enzymatic activity of phospholipase D2 (PLD2) is regulated by phosphorylation-dephosphorylation. Phosphatase treatment of PLD2-overexpressing cells showed a biphasic nature of changes in activity that indicated the existence of “activator” and “inhibitory” sites. We identified three kinases capable of phosphorylating PLD2 in vitro—epidermal growth factor receptor (EGFR), JAK3, and Src (with JAK3 reported for the first time in this study)—that phosphorylate an inhibitory, an activator, and an ambivalent (one that can yield either effect) site, respectively. Mass spectrometry analyses indicated the target of each of these kinases as Y296 for EGFR, Y415 for JAK3, and Y511 for Src. The extent to which each site is activated or inhibited depends on the cell type considered. In COS-7, cells that show the highest level of PLD2 activity, the Y415 is a prominent site, and JAK3 compensates the negative modulation by EGFR on Y296. In MCF-7, cells that show the lowest level of PLD2 activity, the converse is the case, with Y296 unable to compensate the positive modulation by Y415. MTLn3, with medium to low levels of lipase activity, show an intermediate pattern of regulation but closer to MCF-7 than to COS-7 cells. The negative effect of EGFR on the two cancer cell lines MTLn3 and MCF-7 is further proven by RNA silencing experiments that yield COS-7 showing lower PLD2 activity, and MTLn3 and MCF-7 cells showing an elevated activity. MCF-7 is a cancer cell line derived from a low-aggressive/invasive form of breast cancer that has relatively low levels of PLD activity. We propose that PLD2 activity is low in the breast cancer cell line MCF-7 because it is kept downregulated by tyrosyl phosphorylation of Y296 by EGFR kinase. Thus, phosphorylation of PLD2-Y296 could be the signal for lowering the level of PLD2 activity in transformed cells with low invasive capabilities.
