Sugar lactams such as N-(3-phenylpropyl)-1-deoxynojirimycin, 1-deoxynojirimycin, D-glucaro-.delta.-lactam, 6-O-triphenylmethyl-D-gluco-.delta.-lactam, etc. and new derivatives thereof which markedly inhibit metastasis of cancer cells.
摘要:
A known antibiotic, SF-1293 substance and salts thereof have now been found to exhibit high herbicidal effects against a wide variety of herbaceous and woody plants, but they are non-phytotoxic particularly to a useful woody plant, Chamaecyparis obtusa. The herbicidal effects of these SF-1293 substances can be noticeably enhanced by applying in combination with certain known herbicides or compounds having biological activities.

A new antiviral agent is now provided, which contains as the active ingredient at least one known glycine derivative of the formula: ##STR1## wherein R is a hydrogen atom, R' is a group --CH.sub.2 NH.sub.2, --CH.sub.2 NHCONH.sub.2, --CH.sub.2 NHCONHOH, --CH.sub.2 CH.sub.2 PO(OH).sub.2, ##STR2## or R and R' taken together form a group ##STR3## and R" is a hydrogen atom or a lower alkyl group, or a pharmaceutically acceptable salt of said glycine derivative. This antiviral agent is useful for therapeutic prevention and treatment of diseases caused by various kinds of viruses.

摘要:
A known antibiotic, SF-1293 substance and salts thereof have now been found to exhibit high herbicidal effects against a wide variety of herbaceous and woody plants, but they are non-phytotoxic particularly to a useful woody plant, Chamaecyparis obtusa. The herbicidal effects of these SF-1293 substances can be synergistically enhanced by applying in combination with herbicides selected from Linuron, Monolinuron, Monuron and Diuron each known as herbicides of urea derivative class.
摘要:
2-Amino-4-(hydroxy)(methyl)phosphinoylbutyric acid, which earlier nomenclature referred to as 2-amino-4-methylphosphinobutyric acid or its metal salts, or acid-addition salts thereof are used as perennial weeds and brush controlling agents. The L-isomer is twice effective than the racemic acid. The perennial weeds and brush controlling effect may be obtained by foliar application over a prolonged period and maY be surprisingly enhanced by using the compound with a herbicide or synergist selected from the group consisting of choline salt of maleic hydrazide, a phenoxy series herbicide, a benzoic acid series herbicide, 2,3,6-trichlorophenylacetic acid or a salt thereof, (3,5,6-trichloro-2-pyridyl)oxyacetic acid or a salt thereof, N-phosphonomethylglycine or a salt thereof, ethylcarbamoylphosphoric acid or a salt thereof, 2-(1-allyloxyaminobutylidene)-5,5-dimethyl-4-methoxycarbonyl-cyclohexane-1,3-dione, 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea,3-amino-1,2,4-triazole, choline or a salt thereof, and diethylamine or a salt thereof.

Date July 12, 1979This invention relates to a novel process for preparing D,L-2-amino-4-methylphosphinobutyric acid having herbicidal and antifungicidal activities which comprises subjecting acrolein to reaction with a dialkyl phosphonite to synthesize an acetal of an ester of 3-oxopropylmethylphosphinic acid; treating the thus obtained compound with an acid for deacetalization to obtain an ester of 3-oxopropylmethylphosphinic acid and then applying the Strecker's process used for amino synthesis to the thus obtained ester.
