摘要:
Interferon is produced by incubating cells, which are susceptible to producing interferon, prior to induction by an inducer, in a medium containing an effective non-toxic amount of a straight chain, saturated carboxylic acid or a salt thereof.

Novel amine and amidine derivatives of di-0-(n-higher alkyl and alkenyl)-glycerols and -propanediols, and their pharmaceutically acceptable acid addition salts, are useful for combating viral infections in mammals. Of particular interest is 1,3-di-0-(n-hexadecyl)-2-0-(3-aminopropyl)-glycerol, and its pharmaceutically acceptable acid addition salts.
摘要:
KS-substance was obtained as raw material from the cultured mycelium of Daedalea dickinsii KSDD 6 (FERM-P No. 3993), Lentinus edodes KSLE 7 (FERM-P No. 3994) or Lentinus edodes KSLE 28 (FERM-P No. 4196), and by refining this substance a novel substance KS-2-A was obtained. This substance KS-2-A and also the KS-substance as the raw material both enhance the host defense function of the living body.
摘要:
The present invention relates to new chemical compounds which are useful in particular as medicaments. The compounds are derivatives of a quinone endowed with physiological and particularly vitamin activity and of a substituted hydrazine; they correspond to the following general formulas: ##STR1## R.sub.1 and R.sub.2 are identical or different and correspond to the general formula: ##STR2## X represents S, Se, O or NH; R.sub.a, R.sub.b are identical or different and are either H, or a branched or unbranched alkyl radical, or the radical --CH.sub.2 NR.sub.4 R.sub.5 ; in this case R.sub.4 and R.sub.5 are lower alkyl radicals or else form either a morpholine ring or a methylated piperazine ring,R.sub.6 and R.sub.7 may be hydrogen, methyl, allyl, phytyl, farnesyl, geranyl, linayl. R.sub.6 is different from R.sub.7 and one of the two is either hydrogen, methyl or allyl,R.sub.8 and R.sub.9 are identical or different and are --H, --CH.sub.3 or --OCH.sub.3, or form the two together a benzene ring.The compounds in accordance with the invention are endowed with antiviral and vitamin properties and can be administered in therapeutically active doses intravenously, intramuscularly or orally.

The disclosure relates to method for use in the husbandry of meat-producing domestic animals which comprises the oral administration to the animals of a p-benzoquinonedi-imide derivative, or a dihydro derivative or a salt thereof, and to compositions suitable for direct feeding to animals, in the method of the invention, or suitable for dilution with an animal foodstuff to give a supplemented foodstuff suitable for direct feeding to animals in the method of the invention; also to certain of the p-benzoquinonedi-imide derivatives which are novel compounds, and a process for their manufacture.
摘要:
Compounds of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl,R.sub.2 and R.sub.3, together with each other and the nitrogen atom to which they are attached, form a saturated or unsaturated heterocyclic ring system which may optionally contain one or more additional heteroatoms, andA is lower alkylene or aryl-lower alkylene, and nontoxic, pharmacologically acceptable acid addition salts thereof; the compounds as well as their salts are useful as inducers of the formation of interferon.
摘要:
Described herein are novel 6-alkylthio and 6-arylalkylthio purine 3',5' cyclic nucleotides variously exhibiting adenyl cyclase and (in animal studies) tumor inhibitory properties, interferon potentiation, antiviral activity, and the ability to activate adenosine 3',5'-cyclic phosphate-dependent protein kinase while enjoying resistance to phosphodiesterase hydrolysis superior to that of its naturally occuring analog. The compounds are obtained by alkylation of the corresponding 6-thio nucleotide, which is in turn provided by a novel synthetic route.

摘要:
An unusual bacteriophage phi 6, ATCC No. 21781-B, containing a lipid coat and double-stranded ribonucleic acid has been isolated for the plant pathogenic bacterium Pseudomonas phaseolicola ATCC No. 21781. High yields of double-stranded ribonucleic acid may be obtained rapidly and expediently by cultivating a host bacterium for the bacteriophage, infecting the host bacteria with the bacteriophage to provide a lysate and recovering double-stranded ribonucleic acid from the separated bacteriophage. The intact or whole bacteriophage, the bacteriophage with its lipid coat removed, and the isolated nucleic acid have all been found to be effective interferon inducers.
