Synthesis of new arylisoxazole–oxindole conjugates as potent antiproliferative agents

A new series of arylisoxazole–oxindole derivatives (6a–r) were synthesized and evaluated for their antiproliferative activity against human cancer cell lines including non-small cell lung (A549), cervical (HeLa), breast (MCF-7), and prostate (DU-145) cancer cell lines. The synthesized compounds (6a–r) demonstrated excellent to moderate cytotoxicity with IC50 values ranging from 0.82 to 3.69?μm. Some new compounds (6m–r) exhibited profound cytotoxicity better or similar to positive control. More particularly, the compound 6q possesses donating substituent like methoxy group presented at 5-position on D ring exhibited remarkable antiproliferative activity against A-549 (lung cancer) with an IC50 value 0.82?μm. Further studies to determine the mechanistic aspects of these conjugates are under progress.

Novel hybrid molecules of isoxazole chalcone derivatives: Synthesis and study of In Vitro cytotoxic activities

Background: Now-a-days, the model of “hybrid drugs” has acquired recognition in medicine due to their significant role in the treatment of different health problems. Methods: We have synthesized new series of isoxazole-chalcone conjugates (14a-m) by the C

Synthesis, Characterization and biological applications of pyrazole-benzothiazolamine conjugates

Present paper describes the synthesis of some new pyrazole-benzothiazolamine conjugates by molecular conjunction by adopting appropriate synthetic routes. Purification of intermediates and final compounds has been done by recrystallization and chromatographic techniques. Characterization of all the newly synthesized pyrazole-benzothiazolamine derivatives was done by physical and spectral data. The experimental procedure for the preparation of seventeen pyrazole-benzthiazolamine conjugates has been incorporated. Data of synthesized compounds like IR, 1H NMR and Mass spectra were neatly presented. All these compounds were evaluated for their activity against Gram-positive and Gram-negative bacteria and various fungal strains. Anticancer activity has been carried out for the synthesized compounds using HeLa, DU145 and A549 cell lines using MTT assay and we found that the pyrazole-benzothiazolamine conjugates were possess antimicrobial, antifungal and anticancer activities.

Design, synthesis and biological evaluation of novel pyrazolochalcones as potential modulators of PI3K/Akt/mTOR pathway and inducers of apoptosis in breast cancer cells

Cancer has been established as the “Emperor of all maladies”. In recent years, medicinal chemistry has focused on identifying novel anti-cancer compounds; though discovery of these compounds appears to be a herculean task. In present study, we synthesized

Synthesis and biological evaluation of chalcone-linked pyrazolo[1,5-: A] pyrimidines as potential anticancer agents

A series of pyrazolo[1,5-a]pyrimidines substituted at C5 with 1-phenylprop-2-en-1-one (6a-q) and 3-phenylprop-2-en-1-one (7a-k) was synthesized and evaluated for antiproliferative activity. Among them, 6h was found to be the most active compound against the MDA-MB-231 cell line with an IC50 of 2.6 μM. The antiproliferative activity of this series of compounds ranged from 2.6 to 34.9 μM against A549 (lung cancer), MDA-MB-231 (breast cancer) and DU-145 (prostate cancer) cell lines. FACS analysis revealed that these hybrids arrest the cell cycle at the subG1 phase. Western blot analysis and an immunofluorescence assay showed the inhibition of the EGFR and STAT3 axis, which plays an important role in cell survival and apoptosis. Western blot and RT-PCR analyses that displayed an increase in apoptotic proteins such as p53, p21 and Bax and a decrease in the anti-apoptotic proteins Bcl-2 and procaspase-9 confirmed the ability of these hybrids to trigger cell death by apoptosis. Molecular docking studies described the binding of these hybrids to the ATP binding site of EGFR.

Synthesis of (Z)-(arylamino)-pyrazolyl/isoxazolyl-2-propenones as tubulin targeting anticancer agents and apoptotic inducers

A new class of pyrazole and isoxazole conjugates were synthesized and evaluated for their cytotoxic activity against various human cancer cell lines. These compounds have shown significant cytotoxicity with lower IC50 values. FACS results revealed that A549 cells treated with these compounds arrested cells at the G2/M phase of the cell cycle apart from activating cyclin B1 protein levels. Particularly, compounds 9a and 9b demonstrated a remarkable inhibitory effect on tubulin polymerization and showed a pronounced inhibitory effect on tubulin polymerization with IC50 values of 1.28 μM and 0.28 μM respectively, whereas nocodazole, a positive control, has shown lower antitubulin activity with an IC50 value of 2.64 μM. Furthermore, these compounds induced apoptosis by loss of mitochondrial membrane potential, propidium iodide (PI) staining and the activation of caspase-3. Results of a fluorescence based competitive colchicine binding assay suggest that these conjugates bind successfully at the colchicine binding site of tubulin. These investigations reveal that such conjugates containing pyrazole with a trimethoxy phenyl ring and indole moieties have potential for the development of newer chemotherapeutic agents. This journal is

Design and synthesis of pyrazole-oxindole conjugates targeting tubulin polymerization as new anticancer agents

A series of twenty one compounds with pyrazole and oxindole conjugates were synthesized by Knoevenagel condensation and investigated for their antiproliferative activity on different human cancer cell lines. The conjugates are comprised of a four ring scaffold; the structural isomers 12b and 12c possess chloro-substitution in the D ring. Among the congeners 12b, 12c, and 12d manifested significant cytotoxicity and inhibited tubulin assembly. Treatments with 12b, 12c and 12d resulted in accumulation of cells in G2/M phase, disruption of microtubule network, and increase in cyclin B1 protein. Zebrafish screening revealed that 12b, and 12d caused developmental defects. Docking analysis demonstrated that the congeners occupy the colchicine binding pocket of tubulin.

Pyrazole-oxadiazole conjugates: Synthesis, antiproliferative activity and inhibition of tubulin polymerization

A number of pyrazole-oxadiazole conjugates were synthesized and evaluated for their ability to function as antiproliferative agents on various human cancer cell lines. These conjugates are comprised of pyrazole and oxadiazole scaffolds closely attached to each other without any spacer as two structural classes. The Type I class has a trimethoxy substituent and the type II class has a 3,4-(methylenedioxy) substituent on their A rings. Among these conjugates, 11a, 11d and 11f manifest potent cytotoxicity with IC50values ranging from 1.5 μM to 11.2 μM and inhibit tubulin polymerization with IC50values of 1.3 μM, 3.9 μM and 2.4 μM respectively. The cell cycle assay showed that treatment with these conjugates results in accumulation of cells in the G2/M phase and disrupts the microtubule network. Elucidation of zebrafish embryos revealed that the conjugates cause developmental defects. Molecular docking simulations determined the binding modes of these potent conjugates at the colchicine site of tubulin.
