Abstract: Novel mixed agricultural compositions, and methods for their use are disclosed. The agricultural compositions are prepared by a process comprising mixing together a carrier, such as a solid fertilizer or liquid solvent, and a carbohydrate-based surfactant, such as AGRIMUL PG 2069 (Henkel, Dusseldorf, Germany). For example, 8 quarts of surfactant were mixed with one ton of a solid fertilizer. The carrier material can further comprise biologically active agents such as herbicides, insecticides, chemosterilants, nematicides, and fungicides. These mixed agricultural compositions are used to promote the growth of plants in soil and enhance soil bioremediation.

Abstract: Mixed agricultural compositions, and methods for their use are disclosed. The agricultural compositions are prepared by a process comprising mixing together nonionic polyglycol ethers, or oxidation products thereof, and a carrier material. The carrier typically comprises an aqueous or non-aqueous liquid solvent or a solid core material, such as a fertilizer. The carrier may further comprise biologically active agents such as herbicides, insecticides, chemosterilants, nematicides, and fungicides. The agricultural compositions can be used to promote the growth of plants in soil, to improve the control of agricultural pests, and to enhance soil bioremediation.

Abstract: Compounds of formula I or a pharmaceutically acceptable salt thereof: ##STR1## in which formula R.sub.1 represents an aliphatic hydrocarbyl group; Ar represents a substituted or unsubstituted aromatic nucleus;X represents --SO.sub.2 -- or --CO-- andR.sub.2 and R.sub.3 which may be identical or different represent moieties of formula (a), (b), (c), (d), (e), (f), (g), (h) or (i): ##STR2## wherein B represents the residue of a nucleoside base of formula (A), (G), (C), (H) or (T): ##STR3## provided that when R.sub.2 and R.sub.3 both represent an unsubstituted moiety of formula (a) B represents the residue of a nucleoside base which is of formula (A), (G), (C) or (H) are of value for their antiviral activity.

Abstract: The disclosure concerns pyrimidine derivatives represented by the following general formulas [I] and [I'] and having antiviral activity, particularly antiretroviral activity such as anti-HIV activity: ##STR1## and pharmaceutical compositions having antiviral activity and comprising the above-described derivative(s) as an active ingredient.

Abstract: A pyrimidine nucleoside derivative and pharmaceutically acceptable salt thereof specified by the presence of ethyl group or isopropyl group at 5-position of the pyrimidine ring and the presence of a (substituted) phenylthio or a (substituted) benzyl group at 6-position of the pyrimidine ring is provided. The pyrimidine nucleoside derivative and pharmaceutically acceptable salt thereof show a markedly higher anti-retroviral activity than conventional analogous compounds and have a relatively low toxicity against the host cells, and therefore, are useful as an active ingredient of antiviral agent.

Abstract: 6-substitutted acyclopyrimidine nucleoside derivatives represented by the following general formula I: ##STR1## wherein R.sup.1 represents a hydrogen or halogen atom or a group of alkyl, alkenyl, alkynyl, alkylcarbonyl, arylcarbonyl, arylcarbonylalkyl, arylthio or aralkyl; R.sup.2 represents a group of arylthio, alkylthio, cycloalkylthio, aryl sulfoxide, alkyl sulfoxide, cycloalkyl sulfoxide, alkenyl, alkynyl, aralkyl, arylcarbonyl, arylcarbonylalkyl or aryloxy; R.sup.3 represents a hydroxyalkyl group of which alkyl portion may contain an oxygen atom; X represents an oxygen or sulfur atom or amino group; Y represents an oxygen or sulfur atom; and A represents .dbd.N-- or --NH-- or pharmaceutically acceptable salts thereof, processes for their preparation and antiviral agents containing them as active ingredients.

Abstract: The novel substance E-5-(2-bromovinyl)-2'-deoxyuridine and its corresponding iodovinyl derivative are gifted with specific antiviral activities towards herpes simplex virus. They may be synthesized by a condensation reaction followed by separation of anomers.

Abstract: The compound of formula (I): ##STR1## wherein X is CFCl; and C.sub.1-6 alkanoyl esters and/or phosphate esters thereof, is active against herpes viruses.

Abstract: The invention relates to E-5-(2-halogenovinyl)-2'-deoxycytidines, e.g. E-5-(bromovinyl)-2'-deoxycytidine and E-5-(2-iodovinyl)-2'-deoxycytidine. These substances are endowed with specific antiviral activities towards herpes simplex virus and with an extremely low toxicity which makes them useful in antiviral medicines and for treatment of virus diseases in man and animal. They may be synthesized by introduction of an E-5-(2-halogenovinyl) sidechain into 2'-deoxycytidine, or by condensation of a trialkylsilyl derivative of E-5-(2-halogenovinyl)-cytosine with a hydroxyl-protected reactive derivative of 2'-deoxy-D-erythro-pentofuranose.
