An experimental study of 300 mice exposed to pitch(3 gm.dissolved in 10 ml.of 80% benzene solution)obtained from 4 different sources,name- ly Anshan coal-tar pitch,Yu-men petroleum pitch,Dairen petroleum pitch or commonly known as Russian crude oil and the Asia Oil Company, USA,was carried out over a period of 350 days. From the beginning a group of these experimen- tal animals was exposed to artificial sun-ray for 2 hours a day.The results of our experiment indicate that pathological changes of different degrees of severity,such as chronic dermatitis and tumor formation,were the commonest effect of pitch on skin both in the exposed and non-ex- posed groups while the control group(exposed to 80% benzene only)showed only slightly acute dermatitis. The pathological changes as observed both in gross appearances and histological findings are given in detail. The course of tumor formation as found in both the exposed and the non-exposed groups may be classified in the order of time sequence as benign squamous papilloma,malignant squamous papilloma and finally squamous-celled carcinoma; also a few cases of sarcoma and a few cases of so- called“Myoblastoma”. Through the action of photosensitivity to the exposed group,the prolongation of the latent period of tumor formation,the effectiveness in the development of dermatitis and malignant changes in tumors were clearly observed in the process of the pathological changes. The relative potency of the carcinogenic pitch obtained from the above sources has been calculated by means of the statistical analysis of both the incidence and the length of time for the development of the cutaneous tumors.

(一)四种来源不同的沥青(鞍山煤焦油沥青、西北玉门石油沥青、大连石油沥青、和美国亚细亚公司石油沥青)经涂抹小白鼠的实验证明具有引起皮肤各种的病理变化的作用。其中包括慢性渗出性皮炎;慢性炎性上皮结缔组织增生;良性皮肤乳头状瘤;皮肤鳞状细胞癌。此外也引起了少数的肉瘤和“肌母细胞痛”。皮肤瘤发生的潜伏期由62天至406天不等。(二)光感作用可以加剧及加速煤焦油沥青皮肤炎的进展,和发炎皮肤的角化现象。至于对沥青致癌作用本实验未能证实其有显著的影响。(三)根据四种来源不同的沥青所引起皮肤良性与恶性病变的发病率和潜伏期的长短,可将其毒性的强弱顺序排列如下:(1)鞍山煤焦油沥青,(2)美国亚细亚公司石油沥青,(3)大连石油沥青(苏联原油),(4)西北玉门石油沥青。即煤焦油沥青毒性远较石油沥青为强。国产石油沥青的毒性较外产石油沥青的毒性为弱。

Since it is known that some organo-fluorine compounds such as fluoro pyrimidines, are capable of inhibiting the growth of rat tumor,it will be of interest to synthesize and study fluoro-containing amino-acids for the carcinostatic action. ω-Fluoro-a-amino butyric,-valenic and caproic acids are the only fluoro-containing aliphatic amino-acid recorded in literature.We have synthesized β-fluoro-α-amino-propionic acid by the following sequence of reactions: When 2-phenyl-4-chloromethylene-5-azlactone (Ⅰ) was treated...

Since it is known that some organo-fluorine compounds such as fluoro pyrimidines, are capable of inhibiting the growth of rat tumor,it will be of interest to synthesize and study fluoro-containing amino-acids for the carcinostatic action. ω-Fluoro-a-amino butyric,-valenic and caproic acids are the only fluoro-containing aliphatic amino-acid recorded in literature.We have synthesized β-fluoro-α-amino-propionic acid by the following sequence of reactions: When 2-phenyl-4-chloromethylene-5-azlactone (Ⅰ) was treated with anhydrous potassium fluoride in acetylacetone by UV irradiation,the corresponding fluoro-substituted azlactone (Ⅱ)was formed.The latter was hydrolyzed in aqueous alkali to the acrylic acid deri- vative,which was then hydrogenated in the presence of Adam’s catalyst and subsequently hydrolyzed with hydrochloric acid and formic acid mixture.As shown by paper chroma- tography,the product was contaminated with alanine.The latter was completely removed by azobenzene-p-sulfonic acid and followed by treatment with alumina.The β-fluoro-α- amino-propionic acid hydrochloride thus obtained was chromatographically pure.Raasch was unable to get this amino acid by malonic ester synthesis.We have made attempts to synthesize this compound by treating β-bromo-α-benzoylamido-,β-p-tosylhydroxy-α-benzoyl- amido-propionic acid or diethyl α-acetamido-α-dimethylamino-methyl malonate methyl iodide with anhydrous potassium fluoride in various solvents but the attempts was unsuccessful. A series of fluoro-containing aromatic amino-acids with the general formula given were prepared from p-fluorobenzaldehyde. R=H,OH,SH,SR′ 2-Phenyl-4-(p-fluorobenzylidene)-5-azlactone (Ⅳ) was resulted from p-fluorobenzal- dehyde via Erlenmeyer azlactone synthesis underwent an addition reaction with ethyl-or benzylmercaptans in the presence of sodium methoxide with formation of the corresponding β-(p-fluorophenyl)-S-alkyl-N-benzoylcysteine methyl ester (Ⅵ).The latter was hydrolyzed into the free amino acid in the usual way.In the case of addition of ethylmercaptan, the expected Threo-and Erythreo-isomers were separated.β-(p-Fluorophenyl)cysteine (Ⅷ)was synthesized by subsequent debenzylation of β-(p-fluorophenyl)-S-benzylcysteine (Ⅶb)with metallic sodium in liquid ammonia. A modification of the preparation of p-fluorobenzoldehyde,the key intermediate in our synthesis,has been developed. Biological tests of the indicated compounds showed that p-fluorophenyl serine prolonged the life of rat transplanted with Erhlich Ascites but with no effect toward Sarcoma 180. β-Fluoro-α-amino-propionic acid possessed some inhibiting action on the growth of Sarcoma 180 in rats.The biological tests were carried out in the laboratories of Institute of Ex- perimental Biology and Institute of Materia Media,Academia Sinica.
