Abstract
Noscapine an FDA-approved antitussive agent. With low cytotoxicity with higher concentrations, noscapine and its derivatives have been shown to have exceptional anticancer properties against a variety of cancer cell lines. In order to increase its potency, in this study, we synthesized a series of new amido-thiadiazol coupled noscapinoids and tested their cytotoxicity in vitro. All of the newly synthesised compounds demonstrated potent cytotoxic potential, with IC50 values ranging from 2.1 to 61.2 μM than the lead molecule, noscapine (IC50 value ranges from 31 to 65.5 μM) across all cell lines, without affecting normal cells (IC50 value is>300 μM). Molecular docking of all these molecules with tubulin (PDB ID: 6Y6D, resolution 2.20 Å) also revealed better binding affinity (docking score range from -5.418 to -9.679 kcal/mol) compared to noscapine (docking score is -5.304 kcal/mol). One of the most promising synthetic derivatives 6aa (IC50 value ranges from 2.5 to 7.3 μM) was found to bind tubulin with the highest binding affinity (ΔGbinding is -28.97 kcal/mol) and induced apoptosis in cancer cells more effectively.

Abstract
A series of new noscapinoids designed; synthesized and assessed whether its 3-ylidenephthalide and isocoumarin conjugates improved cytotoxicity. Cu-catalysed Sonogashira coupling of N-propargyl noscapine with 2-bromobenzoic acids followed by in-situ substrate-directed 5-exo-dig or 6-endo-dig cyclization produced 3-ylidenephthalide 6 a-6 f and isocoumarin 7 a-7 h analogues in very good yields. In comparison to the lead drug, noscapine, all the newly synthesised derivatives exhibited strong cytotoxic potential in vitro with IC50 ranging from 5.4 μM to 39.5 μM across the evaluated panel of cancer cell lines, without harming normal cells (IC50 >300 μM).

Abstract
Noscapine is a phthalide isoquinoline alkaloid present in the latex of Papaver somniferum and has demonstrated potent antitumor activity in various cancer models. Structural changes in the core molecule of noscapine architecture have produced a number of potent analogs. We have recently synthesized the novel noscapine analogs (3, 4, and 5) with different functional groups appended at ninth position of natural noscapine. The anticancer activity of these compounds has been investigated using various human cancer cell lines such as HeLa (cervical cancer), DU-145 (prostate cancer), MCF-7 (breast cancer), and IMR-32 (neuroblastoma). One of the compounds in this series, 9-ethynyl noscapine (5), has demonstrated good anticancer activity against HeLa cells. Biological studies demonstrated that compound 5 decreased cell viability and colony formation in HeLa cells in a concentration dependent manner. To further uncover the mechanism in detail, we evaluated compound 5 effect on cell cycle progression, microtubule dynamics, and apoptosis. Cell cycle and western blotting analysis revealed that 9-ethynyl noscapine treatment resulted in cell cycle arrest at G2/M and decreased CDK1 and cyclinB1 protein expression. We also observed that 9-ethynyl noscapine (5) treatment leads to disruption in tubulin polymerization and induction of apoptosis by decreasing expression of bcl2, pro-caspase 3, and activation of cytochrome C. Taken together, our results indicate that 9-ethynyl noscapine (5) effectively supresses the growth of cervical cancer cells (HeLa) by disrupting tubulin polymerization, cell cycle progression leading to apoptosis.

Abstract
AbstractIt is of scientific and practical significance to sense and to remove heavy metal ions in the environment. In this work, four BODIPY-based fluorescent polymeric probes with the ability to sense and separate Fe3+ ions have been prepared via thiol-ene click reaction. The polymers have good thermal stability. Meanwhile, the results show that they have selective recognition capabilities only for Fe3+, which are mainly manifested as significant quenching of fluorescence and color modulation under visible light. The sensitivity is good, and the limit of detection reaches as low as 0.14 µM. They can also be used as reversible chemical probes to detect Fe3+. Therefore, the click reaction provides us with a facile method for preparing fluorescent polymer probes.
