The effect of aniline mustard glucuronide (AMG), p-hydroxyaniline mustard (HAM), and aniline mustard (AM), on Walker ascites tumour cells in vitro showed that AM in about 80 times more toxic than its glucuronide but HAM is at least 800 times more toxic. A non toxic dose of AMG became completely
Sprague-Dawley rats bearing 7,12-dimethylbenz[a]anthracene (DMBA)-induced mammary tumors were treated with either of two aromatic alkylating agents, aniline mustard or melphalan, alone or combined with ovariectomy. Both drugs were applied once a week for 8 weeks. Eight-four percent of the tumors
This work reports a newly designed pH-activatable and aniline-substituted aza-boron-dipyrromethene as a trifunctional photosensitizer to achieve highly selective tumor imaging, efficient photodynamic therapy (PDT) and therapeutic self-monitoring through encapsulation in a cRGD-functionalized
The HT29R colonic adenocarcinoma xenograft has been shown to be rich in the enzyme beta-glucuronidase. Experiments in rodent systems have demonstrated a marked anti-tumour effect of the drug aniline mustard (AM) on tumours with high levels of this enzyme (e.g. the plasmacytomas PC5 and PC6). We have
Seventy-eight patients with advanced cancer received an adequate therapeutic trial with aniline mustard (NSC 18429). Significant anticancer activity with clinical benefit was demonstrated in five patients with cancer of the prostate and one patient with renal cancer. beta-glucuronidase levels in
3-(9-Acridinylamino)-5-(hydroxymethyl)aniline (AHMA) is an anti-cancer agent with significant efficacy against murine leukemia and solid tumors. As a DNA topoisomerase inhibitor, AHMA is proposed to form a ternary complex with DNA and topoisomerase and bind to DNA in an intercalative manner. In
Bifunctional alkylating agents are reactive compounds which work by crosslinking DNA, but which have no special affinity for it. A series of acridine-linked aniline mustards of widely-varying alkylator reactivity (5-11), designed as DNA-directed alkylating agents, have been evaluated in various
A series of aniline mustards with a wide range of electron-donating and -withdrawing substituents in the 3- and 4-positions has been synthesized and evaluated for cytotoxicity in cell culture to examine the potential of using nitro group deactivated nitrogen mustards for the design of novel
Several diamino quinoxalines were designed, synthesized and evaluated as anti-tumor agents. Two compounds showed the most potent cytotoxic activities against the leukemia CCRF-CEM cell line (GI(50)<0.01microM) and the ovarian cancer cell line OVCAR-4 (GI(50)=0.03microM), respectively, with
The objective of the study was to analyse the relationship between occupational exposures and risk of pancreatic cancer. Incident cases of pancreatic cancer and hospital controls were prospectively identified and interviewed during the hospital stay. Occupational history was obtained by direct
A gadolinium complex of 1,4,7,10-tetraazacyclododecane-1,4,7-trisacetic acid (DO3A) and benzothiazole-aniline (BTA) of the type [Gd(DO3A-BTA)(H2O)] has been prepared for use as a single molecule theranostic agent. The kinetic inertness and r1 relaxivity (= 3.84 mM(-1) s(-1)) of the complex compare
A novel manganese(II) complex based on an ethylenediaminetetraacetic acid (EDTA) coordination cage bearing a benzothiazole aniline (BTA) moiety (Mn-EDTA-BTA) was designed and synthesized for use as a liver-specific MRI contrast agent with high chelation stability. In addition to forming a
Use of nanomaterials blessed with both therapeutic and diagnostic property is a proficient strategy in the treatment of cancer in its early stage. In this context, our paper reports the synthesis of uniform size N-rich mesoporous carbon nanospheres of size 65-70 nm from pyrrole and aniline precursor
Rhabdoid tumors (RTs) are aggressive pediatric malignancies with poor prognosis that arise due to loss of the hSNF5/INI1 tumor suppressor. Molecular studies indicate that cyclin D1, a downstream effector of INI1 is up regulated in RT, and is essential for this tumor formation. Previously we
