Treatment of patients with triple-negative breast cancer (TNBC) is challenging due to the absence of well- defined molecular targets and the heterogeneity of such disease. In our endeavor to develop potent isatin-based anti-proliferative agents, we utilized the hybrid-pharmacophore approach to
A series of new isatin-thiazoline 3a-h and isatin-benzimidazole 4a-h derivatives were synthesized via condensation of isatin Mannich bases 2a-h with either 2-aminothiazoline or 2-aminobenzimidazole. The structures of the newly synthesized compounds were characterized by spectral data. The
Background: The persistence of breast cancer as the leading cause of mortality among women, coupled with drug resistance to tamoxifen, the standard endocrine therapy for the disease, exacts fixated attention. To this effect, molecular
Development of novel anti-breast cancer agents.Breast cancer, caused by the development of malignant cells in the breast, is the most common invasive cancer and the second leading cause of cancer death in women after lung cancer. One in eight women In connection with our research program on the development of new isatin-based anticancer candidates, herein we report the synthesis of two novel series of thiazolidinone-isatin conjugates (4a⁻n) and thiazolo[3,2-a]benzimidazolone-isatin conjugates (7a⁻d), and in vitro evaluation of their
Isatin is an endogenous indole in mammalian tissues and fluids that is expected to have antitumor effects in human breast cancer cells. Human breast cancer cells (MCF-7) were exposed to isatin at various concentrations (0, 50, 100, 200 µmol/l) for 48 h. Apoptotic features were demonstrated by nuclei
A hybrid pharmacophore approach was used to design and synthesize isatin-benzothiazole analogs to examine their anti-breast cancer activity. The cytotoxicity of these compounds were determined using three different human breast tumor cell lines, MDA-MB231, MDA-MB468, MCF7, and two non-cancer breast
3 series of novel fused heterocyclic systems, viz. triazolo[4,3-a]quinazolin-7-ones (3), 1 2 4 5-tetrazino[4,3-a]-quinazolin-8-ones (5) and Schiff's bases of isatin derivatives with 2-hydrazinoquinazolin-4-ones (7) have been synthesized. Several of them showed variable and promising in vitro
1H-1,2,3-Triazole tethered imidazole-isatin and imidazole-isatin-thiosemicarbazone conjugates were synthesized and evaluated against MCF-7 and MDA-MB-231 cell lines. Antiproliferative activities of the synthesized conjugates revealed an optimum combination of longer alkyl chain length as spacer and
A novel one-pot multicomponent reaction was performed to synthesize different imidazole and benzotriazole (BTA) isatin-based medicinally important compounds using (p-TSA·H2O) as an economical and operative acid catalyst. The yield of the products was found to be up to a maximum of 92%
Fourteen moxifloxacin-isatin hybrids 5, 6 and 13 tethered via 1,2,3-triazole were designed, and synthesized in this paper. The in vitro activities of the synthesized hybrids against a panel of cancer cell lines including HepG2 liver cancer cells, MCF-7, doxorubicin-resistant MCF-7 (MCF-7/DOX) breast
Herein we report the design and synthesis of novel N-substituted isatins-SLC-0111 hybrids (6a-f and 9a-l). A structural extension approach was adopted via N-alkylation and N-benzylation of isatin moiety to enhance the tail hydrophobic interactions within the carbonic anhydrase (CA) IX active site.
Medicinal bioinorganic chemistry is a thriving field of drug research for cancer treatment. Transition metal complexes coordinated to essential biological scaffolds represent a highly promising class of compounds for design of novel target-specific therapeutics. We report here the biological
A new series of quinazolinone compounds 16-34 incorporating isatin moieties was synthesized. The antitumor efficacy of the compounds against MDA-MB-231, a breast cancer cell line, and LOVO, a colon cancer cell line, was assessed. Compounds 20, 21, 22, 23, 25, 27, 28, 29, 30, 31, 32, 33, and 34
A novel class of 4-piperazinylquinoline derivatives based on the isatin scaffold were designed by molecular hybridization approach and synthesized for biological evaluation. Subsequently, the compounds were examined for their cytotoxic effects on two human breast tumor cell lines, MDA-MB468 and
