Biological Evaluation of a Secondary Metabolite, 9-O-methylfusarubin, from Fusarium oxysporum
      
9-O-methylfusarubin was isolated from a novel source, Fusarion oxysporum, and evaluated for its phytotoxic and chlorotic inducing properties in plants as well as its potential as an antineoplastic agent.
      
At the 50 μM dose, the number of viable cells was reduced by 65% suggesting potential antineoplastic effects of 9-O-methylfusarubin.

In continuing our work on sulfabenzothiazoles containing salt-forming groups, 2-sulfanilylamino-benzothiazole 6- and 5-(or 7-)carboxylic acids were obtained. Their sodium salts are very soluble in water and give neutral solutions. Through the same route,it failed to synthesize the corresponding 4-carboxylic acid,starting either from anthranilic acid or its ethyl ester.They did not give o-thioureidobenzoic acid or its ester,but cyclized to benzoylene thiourea(2- sulfhydryl 4-hydroxyl quinazoline).The same compound...

Through the same route,it failed to synthesize the corresponding 4-carboxylic acid,starting either from anthranilic acid or its ethyl ester.They did not give o-thioureidobenzoic acid or its ester,but cyclized to benzoylene thiourea(2- sulfhydryl 4-hydroxyl quinazoline).The same compound was obtained from the hydrolysis of α-o-carboxyphenyl β-benzoyl thiourea and from the ammoniolysis of o-isothiocyanobenzoic acid. Attempt to cyclize α-o-carboxyphenyl β-benzoyl thiourea by bromine to 2- benzamido-benzothiazole 4-carboxylic acid also failed,and the desulfured cyclized compound was identified to be 2-benzoyl benzoylene urea. We have,at the same time,cleared up the diversed results of H.Rupe and G.M.Dyson et al.and identified the structure of the Douglass and Dains' compound.

1.自对位和间位氨基苯甲酸综合了相应的具有羧基的磺胺苯并噻唑。它们的钠盐在水中溶解度极大,溶液呈中性。2.白间-硫脲基苯甲酸导出的苯并噻唑,其环化并合地位没有确定。3.自-氨基苯甲酸或它的乙酯依同样途径综合,得不到相应的苯并噻唑,产物是苯并嘧啶类型化合物。

Unlike amines and alcohols reacting with acylisothiocyanates to form acylthioureas andacylthiourethans respectively as the only products,phenols reacted,in general,with the samereagents in two different ways,namely:(Ⅰ)Acylation:(Ⅱ) Addition:where R=C_6H_5,p-BrC_6H_4,and R'=CH_3,H,Cl,COOH,NO_2,etc.In some cases,the former reaction occurred predominately.With phenols containinsproton-repelling groups,such as o-nitrophenol,p-nitrophenol,2,4-dinitrophenol,picric acid,etc.,which react with arylisocyanates with difficulty,however,addition...

Unlike amines and alcohols reacting with acylisothiocyanates to form acylthioureas andacylthiourethans respectively as the only products,phenols reacted,in general,with the samereagents in two different ways,namely:(Ⅰ)Acylation:(Ⅱ) Addition:where R=C_6H_5,p-BrC_6H_4,and R'=CH_3,H,Cl,COOH,NO_2,etc.In some cases,the former reaction occurred predominately.With phenols containinsproton-repelling groups,such as o-nitrophenol,p-nitrophenol,2,4-dinitrophenol,picric acid,etc.,which react with arylisocyanates with difficulty,however,addition reaction took place readilyand gave acylthiourethans in high yields.o-Aminophenol reacted with aroylisothiocyanates forming corresponding aroylthiourea insteadof urethan.In basic medium acetoacetic ester reacted with p-bromobenzoylisothiocyanate yielding anaddition compound,which showed no unsaturation.It was,therefore,suggested that theaddition took place between isothiocyanate residue and the active hydrogen of the keto formrather than the enol form of the ester.Malonic ester reacted with the reagent in the same fashion.

1. 芳酰异硫氰与酚类作用时,反应一般以两种类型进行,即酰化与加成。某些情况下酰化反应占优势。但是硝基酚能够顺利地与芳酰异硫氰起加成反应。所得到的酰氨基硫代甲酸酚酯均为有一定熔点的良好晶体。2. 鄰氨基酚与芳酰异硫氰作用时,由氨基起加成反应得到对应的芳酰基硫脲。3. 含活泼亚甲基的化合物,如乙酰乙酸乙酯及丙二酸二乙酯,与对溴苯甲酰异硫氰作用时,可以得到亚甲基上活泼氢原子与试剂起加成反应的产物。

作者研究了三个类型的 Sb~Ⅲ“试剂:(1)含有酸性基的化合物,(2)所谓 Caille-viel 试剂,(3)含有两个位酚基的化合物。由结果得出,(1)和(2)两个类型的试剂的灵敏度不高,并且不能用变动结构式来提高灵敏度。第(3)类试剂,即含有两位酚基的化合物显然是最有希望的 Sb~Ⅲ试剂。它们的反应是相当灵敏的。作者制备了几类有色化合物,其中二羟基荧光黄和三羟基金色素是满意的 Sb~Ⅲ试剂。
