A new pyrrole based small molecule from Tinospora cordifolia induces apoptosis in MDA-MB-231 breast cancer cells via ROS mediated mitochondrial damage and restoration of p53 activity.

Only registered users can translate articles

Approximately 15% of globally diagnosed breast cancers are designated as triple negative breast cancer (TNBC). In this study, we investigated the effect of the natural compound, Bis(2- ethyl hexyl) 1H-pyrrole-3,4-dicarboxylate (TCCP), purified from Tinospora cordifolia on MDA-MB-231, a TNBC cell

Pyrrole alkaloids with potential cancer chemopreventive activity isolated from a goji berry-contaminated commercial sample of African mango.

Only registered users can translate articles

Bioassay-guided fractionation of a commercial sample of African mango (Irvingia gabonensis) that was later shown to be contaminated with goji berry (Lycium sp.) led to the isolation of a new pyrrole alkaloid, methyl 2-[2-formyl-5-(hydroxymethyl)-1H-pyrrol-1-yl]propanoate, 1, along with seven known

Inhibition of MMP-9 transcription and suppression of tumor metastasis by pyrrole-imidazole polyamide.

Only registered users can translate articles

Matrix metalloproteinase (MMP)-9, the 92-kDa type IV collagenase, contributes to tumor invasion and metastases, and strategies to down-regulate its expression could ultimately be of clinical utility. A pyrrole-imidazole (PI) polyamide that targets the activator protein-1 (AP-1)-binding site of the

A pyrrole-based natural small molecule mitigates HSP90 expression in MDA-MB-231 cells and inhibits tumor angiogenesis in mice by inactivating HSF-1.

Only registered users can translate articles

Heat shock proteins (HSPs), molecular chaperones, are crucial for the cancer cells to facilitate proper functioning of various oncoproteins involved in cell survival, proliferation, migration, and tumor angiogenesis. Tumor cells are said to be "addicted" to HSPs. HSPs are overexpressed in many

Synthesis and cytotoxicity of 2,4-disubstituted and 2,3,4-trisubstituted brominated pyrroles in murine and human cultured tumor cells.

Only registered users can translate articles

The 2,4-disubstituted and 2,3,4-trisubstituted brominated pyrroles were successfully prepared and demonstrated potent cytotoxicity against the growth of suspended murine and human tumors, i.e. leukemia and lymphomas, acute monocytic leukemia, and HeLa-S3 uterine carcinoma. The brominated compounds

Evaluation of thieno[3,2-b]pyrrole[3,2-d]pyridazinones as activators of the tumor cell specific M2 isoform of pyruvate kinase.

Only registered users can translate articles

Cancer cells have distinct metabolic needs that are different from normal cells and can be exploited for development of anti-cancer therapeutics. Activation of the tumor specific M2 form of pyruvate kinase (PKM2) is a potential strategy for returning cancer cells to a metabolic state characteristic

Synthesis and Anti-cancer Activity of 3-substituted Benzoyl-4-substituted Phenyl-1H-pyrrole Derivatives.

Only registered users can translate articles

BACKGROUND Cancer is considered a major public health problem worldwide. OBJECTIVE The aim of this paper is to design and synthesis of novel anticancer agents with potent anticancer activity and minimum side effects. METHODS A series of pyrrole derivatives were synthesized, their anti-cancer

Tumor Repression of VCaP Xenografts by a Pyrrole-Imidazole Polyamide.

Only registered users can translate articles

Pyrrole-imidazole (Py-Im) polyamides are high affinity DNA-binding small molecules that can inhibit protein-DNA interactions. In VCaP cells, a human prostate cancer cell line overexpressing both AR and the TMPRSS2-ERG gene fusion, an androgen response element (ARE)-targeted Py-Im polyamide

A Pyrrole-Imidazole Polyamide Is Active against Enzalutamide-Resistant Prostate Cancer.

Only registered users can translate articles

The LREX' prostate cancer model is resistant to the antiandrogen enzalutamide via activation of an alternative nuclear hormone receptor, glucocorticoid receptor (GR), which has similar DNA-binding specificity to the androgen receptor (AR). Small molecules that target DNA to interfere with

Facile Preparation of Doxorubicin-Loaded and Folic Acid-Conjugated Carbon Nanotubes@Poly(N-vinyl pyrrole) for Targeted Synergistic Chemo-Photothermal Cancer Treatment.

Only registered users can translate articles

We developed a bifunctional nanoplatform for targeted synergistic chemo-photothermal cancer treatment. The nanoplatform was constructed through a facile method in which poly(N-vinyl pyrrole) (PVPy) was coated on cut multiwalled carbon nanotubes (c-MWNTs); FA-PEG-SH was then linked by thiol-ene click

Enhancement of dendritic cell-tumor fusion vaccine potency by indoleamine-pyrrole 2,3-dioxygenase inhibitor, 1-MT.

Only registered users can translate articles

OBJECTIVE Dendritic cell (DC)-based cancer vaccines are currently being evaluated as novel anti-tumor vaccination strategies, but in some cases, they are demonstrated to have poor clinical efficacies than anticipated. A potential reason is immune tolerance due to the immunosuppressive enzyme,

Design, synthesis and anti-cancer activity of pyrrole-imidazole polyamides through target-downregulation of c-kit gene expression

Only registered users can translate articles

Pyrrole-imidazole polyamide (PIP) can specifically bind in the B-DNA minor groove that has been used in several biological applications, such as anti-cancer activity, gene expression and translation control, and visualization of complex genomic areas. c-kit is a family member of the Tyrosine Kinase

Design, synthesis and anti-tumour activity of new pyrimidine-pyrrole appended triazoles.

Only registered users can translate articles

The new pyrimidine-pyrrole scaffolds (7a-7m) with substituted 1,2,3-traizole moiety were synthesized in good to mild yields and subjected for anti-cancer activity against melanoma and breast cancer cell lines using MTT assay. The compounds 7f and 7m exhibited highest anti-cancer activity against

CORRIGENDUM A Promising Anti-Cancer and Anti-Oxidant Agents Based on the Pyrrole and Fused Pyrrole: Synthesis, Docking Studies and Biological Evaluation.

Due to an oversight, one of the author's name was published wrong in the article entitled "A Promising Anti-Cancer and Anti-Oxidant Agents Based on the Pyrrole and Fused Pyrrole: Synthesis, Docking Studies and Biological Evaluation" in "Anti-Cancer Agents in Medicinal Chemistry, 2015,

Synthesis and biological evaluation of pyrrole-based chalcones as CYP1 enzyme inhibitors, for possible prevention of cancer and overcoming cisplatin resistance.

Only registered users can translate articles

Inhibitors of CYP1 enzymes may play vital roles in the prevention of cancer and overcoming chemo-resistance to anticancer drugs. In this letter, we report synthesis of twenty-three pyrrole based heterocyclic chalcones which were screened for inhibition of CYP1 isoforms. Compound 3n potently
