USE OF MEMBRANE MODULATORS AND PRODUCTS COMPRISING SUCH MEMBRANE MODULATORS

Abstract: Use of certain water-soluble compounds known as such and having the formula R<1> - CO - NH - R<2> for the modulation of membrane dependent metabolism processes within living cells, in particular with relation to transport phenomena and cell procedures which are induced or influenced by active agents supplied from outside the cell, products containing these substances for the above described uses and processes using these products.

Description: Use of membrane modulators and products comprising such membrane modulators. The invention is related to the use of known compounds for the modulation of membrane dependent metabolism processes with living cells. Of particular importance are product transport phenomena as well as certain cell processes induced by active agents supplied from outside of the cell (f.i. growth promoting agents, growth inhibiting agents, herbicides, fungicides, bactericides, fertilizers). By the combination of the membrane modulators according to the invention with such compounds it is possible to influence the activity of these compounds, probably by an infl.μence upon these cell processes in the desired direction,, :i.e. they enlarge, suppress, accelerate or slow down such cell processes. For instance, the following cell processes may be modulated by the compounds of the invention: - the transporation of nutriments, - the transport of hydrogen ions, - the transportation of water and/or ions, - the endocytose and exocytose, - the turn over speed of .membrane controled enzymes - the transport of active agents (growth agents, growth - inhibitors and the like). Surprisingly, the cell membrane of plant cells or animal cells or fungus cells may be influenced in a desired manner. Thus, plants may be caused to a quicker growth when influencing the growth-limiting factors of the uptake of nutriments. On the other hand, cells which have lost the ability of controlled growth such tumor cells thus could be inhibited in their undesired growth properties. The uptake of agents influencing the development of cells such as drugs or plant protecting agents could substantially be increased. Many attempts therefore have been made to find compounds which influence cell membranes in the above mentioned manner. In particular, those compounds have to be mentioned which are components of the membrane or present in the membranes such as the phospholipids making up to 70 % of the cell membrane. Fractions of phospholipids have also been tried. European patent application ΞP 7^ 251 describes that particular fractions of phospholipids and triglycerides may lower the fluidity of cell membranes. The following deseases or changes in the metabolism are described to be possibly influenced: Alcoholism, drug dependency, disturbances in the immun system, disturbances of the nervous system, high blood pressure, atherosclerosis. In the German published patent application DE-OS 31 50 296 there is described the use of quaternary ammonium salts such as choline chloride to influence the fluidity of membranes in the plant and thus make them more sensitive to cold temperatures. - J - As described in PR0T0PLA3MA 50., (1976), pgs. 229 ff., tomato plants by the addition of ethanolamine, a component of the phospholipid cephaline, may be made less sensible to damages caused by low temperatures. In the DDR patents DD 209340, DD 209338, DD 208038 and DD 209339 i is reported that choline chloride and ethanolamine may be used alone or together, possibly in combination with other substances t influence positively the water household and the growth of the plants. The disadvantage of these' substances is that the desired effect only is obtained when using them at high concentration. Thus, DDR patent DD 209339 describes that choline and ethanolamine are used in amounts of ό kg/ha. These high amounts are not only * uneconomical but undesirable .also environmentally. It is therefore an object of the present invention to find compounds which at dosages as small as possible modulate the cell membranes, in ' particular modulate ceil membrane dependent metabolism processes within living cells, in particular with relation to transport phenomena and cell procedures which are induced or influenced by active agents supplied from outside the cell and processes in the cell membrane which not only unspecifically lower the fluidity of the membrane wall but, dependent upon the applied dosage by way of an increase or : " lowering of the permeability of cell membranes, influence the : .- processes occuring in the ceil in an optimal manner and degree to produce the desired result. It is most desirable and a prerequisite environmentally of such a -influence that such products are non-toxic. They should be easily available or easy to be produced and formulated. According to the invention, there are used to modulate cell membranes as above described, the selected group of simple water- soluble, partially naturally occuring compounds according to the general Formula I R 1 - CO - NH - R' -] wherein R is a straight or branched, saturated or unsaturated alkyl with 1 to 6 carbon atoms and R is an alkyl with 1 to 3 carbon atoms, a hydroxyalkyl with 1 to 3 carbon atoms or an acyloxyalkyl with 1 to 3 carbon atoms both in the acyl and in the alkyl group. Preferably, R 1 is methyl, ethyl or propyl and R2 is methyl, ethyl, 2-hydroxylethyl, 2-acetyloxyethyl, 2-hydroxypropyl or 3-hydroxypropyl. Particularly preferred are N-acetylethanolamine and N-methylacetamide. They may be used together. If so, this mixture contains the components in a weight proportion of from 1:10 to 10:1. The cell membrane modulating properties of the compounds used according to the invention are shown by the following tests and test results: 1. In a Petri disk there are mixed a potato dextrose agar substrate with 0.1 ppm of 2.4>-dichloro- -(pyrimidin-5-yI)- benzhydryl alcohol (generic name: Fenarimol) . This active agent is a known product, against piantpathogenic fungi in particular. A suspension of the fungus Botrytis cinera is mixed with an increasing amount of N-acetylethanolamine and two droplets of thes mixtures are placed in the middle of the Petri disk. An indication of the degree of activity of the fungicidal compound alone or in combination with the products according to invention is the diameter of the corona infected by the fungus. The activity of the additive according to the invention is shown in the following Tabl Table I Diameter of the infected corona in mm 54 54 35 30 30 40 58 70 80 Concentra- 0.003 0.01 0.03 0.1 0.3 1 3 10 30 tion of N-acetyl¬ ethanolamine in ppm Since the fungicide may only be active by an uptake of the active agent into the fungus cells, the variable activity of the fungicide shows the change in the rate of transportation of the fungicide through the cell membrane of the fungus. This means that by the addition of N-acetylethanolamine in small amounts the is no increase in fungicide transport through the fungus cell membrane, at mean amounts there is a substantial increase of the permeability of the cell wall and, thus, fungicidal activity, and at high amounts there is a decrease of the permeability of the " ce membrane or of the rate of transportation of the active agent through the cell membrane. In a further test, human cancer cells which are kept in culture ( so-called KB - cells) are treated with radio-actively marked thymiάine and methionine in combination with varying amounts of N-ace-tylethanol- a ine. The cells are separated from the substrat and the amount of the absorbed thymidine and methionine is determined. The determined values show how the rate of transportation of these two substances through the cell membrane into the cell is influenced in relation to the concentration of the added N-acetylethanolamine: Uptake into the cell in % Concentration of Methionine Thymidine N-acetylethanolamine 0 / umole 0.1 ,umole +19 +20 1 /umole -42 -37 10 ,umole -77 -62 As follows from the above table, small amounts of N-acetylethanol¬ amine positively influence the rate of transportation through the cell membrane while increased amounts decrease the uptake of the- two compounds. The compounds of the formula R 1 - CO - NH - R 2 wherein R' ana R *** - have the above given meaning, may be used in accordance to the present invention in all instances where the cells are open to a direct treatment of the development and/or the metabolism of which is to be influenced and modulated. This treatment may be with these cell modulators alone (f.i. wher nutritive agents are available by the natural surrounding) or in combination with active agents or nutritive agents. Active agents - 7 - may be drugs or various plant protective agents (herbicides or, i particular and most preferred, fungicides). Nutritive agents may trace elements and compounds, which are necessary for cell nutrition. Thus, the compounds of the above formula may be used, generally expressed, to influence: - the activity of plant protective agents, . - the activity of fertilizers, - the uptake of natural nutritive agents from the soil and atmosphere, with the increase of plant growth, - the growth of microorganisms and yeasts and, thus, of fermentation processes, - the activity of antimycotica against humane pathogenic germs. Particularly preferred is the combination of the acid amides R 1-CO-NH-R2 with known fungicides or fertilizers. Most preferred is the combination of the acid amides R 1-CO-NH-R2 with known fungicides. In the new products according to the invention to treat plants, t N-hydroxyalkyl alkanoic acid amides contained therein increase th effectivity of the fungicides contain therein and combined therwith, while the N-hydroxyalkylalkanoic amides themselves do n produce an own fungicidal activity. Preferably, there may be used as N-hydroxyalkylalkanoic acid amides: N-(2-hydroxyethyl)-, N-(2-acetoxyethyI)-, N-(2-hydroxypropyl)- or N-(3-hydroxypropyl- alkanoic acid amides acetic acid. Particularly preferred is N-(2-hydroxyethyl)- acetamide and N-methylacetamide each, alone or in admixture there in weight proportion of 1:10 to 10:1. The weight proportion between the active agent, most preferred the fungicidally active agent, and the N-hydroxyalkyl alkanoic ac amide is between 1:0.1 to 1:6. This weight proportion is dependent upon the amount. of active agent and, most preferred, the fungicide to be applied. Thus, with an amount of 0.5 to 1.5 kg of active agent, most preferred of fungicide, per ectar (= 10000 m ) the weight proportion between the active agent and, most preferred the fungicidally active compound, and the N-hydroxyalkyl alkanoic acid amide is 1:0.1 to 1:2. With an amount up to 0.5 kg of the active agent - and most preferred of the fungicidally active component - per ectar, the weight proportion of the active agent - most preferred of the fungicidally active component - to N-hydroxyalkyl alkanoic acid amide is 1:1 to 1:6.

Most preferred herbicides are Amitrol, Simazin, MCPA, Chlormequat chlor ide, Ethephon and Acifluorfeπ-sodium-salt use d alone or in combination of several of them as described in the following Examples 1, 2 and 4. The new herbicidal compositions may be applied by standard methods, for example as soil or leaf herbi¬ cides or as systemic herbicides or contact herbicides ' before or after sowing or after emergence, according to requirements. The new herbicidal compositions are used primarily for controlling eeds and wild grasses ' such as, for example, Alopeurus myosuroides, Bromus tectorum, Cyperus rotundus, Digitaria sanquinalis, Echinochlora crus galli, Eleusine indica, Festuca ovina, Lolium perenne, Phleum protense, Setaria italica, Poa annua, Setaria viridis, Sorghum halepense, Abutilon theophrasti, Amaranthus retroflexus, Anthemis arvensis, Chenopodium album, Chrysanthemum segetum, Convαlutus arvensis, Agropyron repens, Apera pica-venti, Arrhenaterum elastius bulbosum, Pennisetum clandestinum, Ischaemum rugosum, Rottboellia exaltata, Imperata cylindrica, Poa trivialis, Leptochloa filiformis, Setaria faberii, Galium aparine, Cirsium arvense, Atriplex spp., which hinder or are harmful to the cultivation of useful plants in one-crop systems. Examples of useful plants which may be protected against weeds and wild grasses are oats, barley, rice, millet, wheat, corn, sugar beet, cane s-ugar, potatoes, soya beans, cotton, tobacco, coffee, fruit, vegetables or vines. The use of the compounds R1-CO-NH-R2 as membrane modulating substances in accordance with the present invention gives extremely good results also in combination with fertilizers. As main fertilizer or nutritive product there may be used known nitrogen fertilizers, known phosphate fertilizers, known potassium fertilizers or mixtures thereof. Such known nitrogen fertilizers are for instance ammoniumsulphate, calcium ammoniu nitrate, urea, urea-aldehyde-condensation products, nitrogenmagnesiumoxide products, ammoniu sulphatenitrate, calciumnitrate or calciumcyanamide. Known phosphate fertilizers are for instance superphosphate, doublesuperphosphate, triplesuperphosphate, thomasgrain, thomasphosphate, glowphosphate, rhenaniaphosphate, dicalciumphosphate or crudephosphate. Useful potassium fertilizers are potassiumchloride, potassiu sulfate, potassiummagnesiumoxide. Further main nutritive agents may be calciumcarbonate such as chalk; calciumoxide, magnesiumoxide, kieserit or dolomit. there may be further admixed organic components such as guano, fish-meal, bown- eal, lignin or peat. Further, there may be admixed known derivatives of traceelements such as manganese, zinc, iron, copper and molybdenum. For instance, zincoxide, zincsulfate, zinccarbonate, copperoxide, olybdenumsulfate and borates of such elements. The compounds of formula I may be used alone or combined with an active agent or in mixtures, which are produced before using them. Thus, Example 31 illustrates the use of N-hydroxyethylacetamide alone, i.e. without combining it with another active agent. The membrane modulating properties of N-hydroxyethylacetamide is used such that the uptake of naturally occuring nutriments by the plants from the soil is increased. This produces a distinct increase in the weight of green parts in these cultivated plants. The production and use of products consisting of a combination of usual active agents and one or several compounds of formula I, according to the invention, is described in the following examples. According thereto, the compounds of the general formula I are formulated together with active agents or nutriments as products ready for use. It is however also possible to use two products separately, one of the products containing the active agent or nutriment and the other containing the compound of formula I. The user of the combination in accordance with the invention may mix both products in the correct proportion immediately before use, for instance in the presence of water, as is usual in agriculture. In some cases it may be preferable to use several compounds of formula I as membrane modulating agent alone or together with active agents in accordance with the present invention. In this ca » se it is most preferred to use together N-methylacetamide and N-hydroxyethylacetamide in a weight proportion of from 1:10 to 10:1. The present invention is further directed to a process for producing antibiotics etc. penicillins or cephalosporins by fermentation. In this process known process conditions for such a fermentation process are applied and there is added to the f.ermentation broth one or several products of the general formula in a concentration of 5 to 100 /U mole/l. By adding a compound according to formula I to the fermentation broth in the above amount there is considerably increased the yield in the desired penicillin compound. Still furthermore, the present invention is related to a process for microbiological upgrading agricultural waste products by the application of known process * conditions for such processes with an by adding one or several products according to the general formula I to the fermentation mixture or the like product started from in this process in a concentration of from 0.01:1 % , in relation to the solids content of the fermentation mixture. Still furthermore, the invention is directed to a process for cultivating yeast. Again, known conditions for such processes are applied and, according to the invention, there are added to the nutritive solution one or several products according to the general formula I in a concentration of 5 to 250 ,umole/l. Finally, the invention is directed to a process for combating humanpathogenie germs with antimykotic ag-ent-s. Again, known conditions for such processes are applied and, according to the invention, the antimykotic agent is combined with one or several products according to the general formula I in a concentration of from 0.03 to 0.5 % . It is surprising that the effectivity of th antimykotic agent is considerably increased when applying the antimykotic agent in combination with the cell modulating agents according to the present invention in the above specific amounts o in combination product the amount of antimykotic agent may be decrease with producing the same effect as with the antimykotic agent alone. The following examples illustrate the products according to the present invention and their use in modulating cell membranes.
