TLDR
N -[4-(5-Nitro-2-furyl)-2-thiazolyl]formamide was fed to 50 female 5-week-old Swiss mice at a dose of 0.094% by weight of diet for 46 weeks, followed by 7 weeks of the control diet.
Abstract
N -[4-(5-Nitro-2-furyl)-2-thiazolyl]formamide was fed to 50 female 5-week-old Swiss mice at a dose of 0.094% by weight of diet for 46 weeks, followed by 7 weeks of the control diet. Fifty-six mice received only the control diet. Thirty-three test mice survived 40 weeks or longer and had the following tumor incidences: urinary bladder, 31/33; generalized leukemia, 23/33; lung, 6/33; and 1 uterine tumor. In the controls, the following tumor incidences were found: generalized leukemia, 15/44; and lung, 1/44.

A carcinogenic potency database of the standardized results of animal bioassays

TL;DR: The Carcinogenic Potency Database is presented, which includes results of about 3000 long-term, chronic experiments of 770 test compounds, which provides quantitative information about negative tests and readily permits comparisons of carcinogenic potency and many other aspects of cancer tests.

Intravesical and Systemic Chemotherapy of Murine Bladder Cancer

Mark S. Soloway
- 01 Aug 1977 - 
TL;DR: It is hoped that information gained from these animal models, which allow evaluation of many drugs within a relatively short period of time, will identify drugs effective in transitional cell carcinoma and lead to therapeutic trials in patients with bladder cancer.

On the mutagenicity of nitrofurans

TL;DR: Three nitrofurans were tested for ability to induce revertants of E. coli WP2 and its uvrA - derivative from tryp - to tryp + and all proved to be mutagnic while two furan analogues (lacking the nitro- group) proving to be inactive.

Spontaneous Tumors in Sprague-Dawley Rats and Swiss Mice

TL;DR: The percentage of female rats with tumors was almost double that of males, which difference was accounted for chiefly by the high incidence of mammary tumors in the females, and the largest number of rat tumors occurred in the endocrine system, mainly the pituitary and adrenal glands.

Susceptibility of urothelium to neoplastic cellular implantation.

TL;DR: This study sought to determine whether or not transitional carcinoma cells can adhere and progressively grow on normal or inflamed bladder urothelium and offers a model to investigate modalities to prevent tumor cell implantation.

The production of carcinoma of the urinary bladder in rats by feeding N-[3-(5-nitro-2-furyl)-2-thiazolyl]formamide.

TL;DR: The first nitrofuran derivative which has been found to be a bladder carcinogen, and the compound appears to be one of the most effective bladder carcinogens for this species.

Pathogenesis, Histology, and Transplantability of Urinary Bladder Carcinomas Induced in Albino Rats by Oral Administration of N-[4-(5-Nitro-2-furyl)-2-thiazolyl]formamide

TL;DR: N-[4-(5-Nitro-2-furyl)-2-thiazolyl]formamide appears to be one of the most effective urinary bladder carcinogens for both male and female Sprague-Dawley rats, providing carcinomas exhibiting all criteria of malignancy.
