A series of biodistribution studies were conducted with the radiotracer, [(18)F]N-(4'-fluorobenzyl)-4-(3-bromophenyl)acetamide, [(18)F]1 in nude mice bearing tumor xenografts of the mouse mammary adenocarcinoma, line 66. This radiotracer has a high affinity for both sigma(1) and sigma(2) receptors.
Hypoxia occurs to a variable extent in a vast majority of rodent and human solid tumors. It results from an inadequate and disorganized tumor vasculature, and hence an impaired oxygen delivery. A probe for the non-invasive detection of tumor hypoxia could find important utility in the selection of
Now clear evidences are available to support the hypothesis that inflammation accelerates the conditions including events and molecules that reach to various types of cancers. Inflammation is a normal response to infection containing the innate and adaptive immune systems. However, when allowed to
Background: In recent years, discovery and development of new drugs play a critical role in cancer therapy.
Objective: In this study, the effect of MPAEA and p-acetamide on
Breast cancer is the most dominating malignancy in females worldwide. Treatment with conventional chemotherapeutics is associated with severe adverse effects. Thus need of new compounds, with better therapeutic potential and lesser side effects still exist. In this context the present study is
In recent years, combination chemotherapy is a primary strategy for treating lung cancer; however, the issues of antagonism and side effects still limit its applications. The development of chemosensitizer aims to sensitize chemoresistant cancer cells to anticancer drugs and therefore improve the
BackgroundWe investigated the role of reactive oxygen species (ROS) in the anticancer mechanism of N-benzyl-2-nitro-1-imidazole-acetamide (BZN), a drug used in Chagas' disease treatment. MethodsBALB/c mice, inoculated with Ehrlich ascites carcinoma (EAC), were treated with BZN or BZN + Nacylcysteine
In this study, a series of thiosemicarbazide derivatives 12-14, 1,2,4-triazol-3-thione derivatives 15-17 and compounds bearing 2-(4H-1,2,4-triazole-3-ylthio)acetamide structure 18-32 have been synthesized starting from phenolic compounds such as 2-naphthol, paracetamol and thymol. Structures and
Several anti-tubulin agents were introduced for the cancer treatment so far. Despite successes in the treatment of cancer, these agents cause toxic side effects, including peripheral neuropathy. Comparing anti-tubulin agents, indibulin seemed to cause minimal peripheral neuropathy, but
While the treatment of gastrointestinal stromal tumors (GISTs) has been revolutionized by the application of targeted tyrosine kinase inhibitors capable of inhibiting KIT-driven proliferation, diverse mutations to this kinase drive resistance to established therapies. Here we describe the
Starting from our previously developed c-KIT kinase inhibitor CHMFL-KIT-8140, through a type II kinase inhibitor binding element hybrid design approach, we discovered a novel c-KIT kinase inhibitor compound 18 (CHMFL-KIT-64), which is potent against c-KIT wt and a broad spectrum of
A novel synthesis of the translocator protein (TSPO) ligand 7-chloro-N,N,5-trimethyl-4-oxo-3-phenyl-3,5-dihydro-4H-pyridazino[4,5-b]indole-1-acetamide (SSR180575, 3) was achieved in four steps from commercially available starting materials. Focused structure-activity relationship development about
Photodynamic therapy (PDT) of tumors can create hypoxia when oxygen is depleted by photochemical consumption or the oxygen supply is compromised by microvascular damage. However, oxygen is a requirement for PDT, and hypoxia during illumination can lead to poorer tumor response. As such, sensitive
Development of various cost-effective contrast agents for targeted tumor computed tomography (CT) imaging still remains a great challenge. Herein, we present a facile approach to forming folic acid (FA)-targeted multifunctional gold nanoparticles (AuNPs) using cost-effective branched
The activity of indole-3-acetamide (IAM) hydrolase from rice cells was enriched ca. 628-fold by gel filtration and anion exchange column chromatography. The molecular masses of the IAM hydrolase estimated by gel filtration and sodium dodecyl sulfate polyacrylamide gel electrophoresis were
