Abstract

Ribonucleases (RNases) are highly active, easily used and extremely stable enzymes. Together with detergents, RNases deactivate and destroy irreversible RNA viruses. Agents containing RNase(s) and detergents are therefore suitable for disinfecting instruments, clothing and surfaces from contaminating RNA viruses. Special application forms for coating the skin surfaces of human beings, animals or plants reduce the risk of infection from RNA viruses. Agents with RNases and detergents, possibly combined with substances, may be regarded as "anti-infectives against RNA viruses (=aiRVi).

Beschreibung description

RNasen sind hochaktive, anspruchsarme und extrem stabile Enzyme. RNasen inaktivieren in Zusammenwirkung mit Deteroentien (= Mittel mit RNasen) RNA-Viren rasch und irreversibel: RNases are highly active, low-demanding and extremely stable enzymes. RNases quickly and irreversibly inactivate RNA viruses in conjunction with detergents (= agents with RNases):

RNasen können mit verschiedensten herkömmlichen flüssigen oder getrockneten Substanzen zur Reinigung, Desinfektion oder Körperpflege kombiniert oder als neue optimierte Reagentien in verschiedenen Kombinationen mit neuen Formulierungen angewendet werden. RNases can be combined with a wide variety of conventional liquid or dried substances for cleaning, disinfection or personal care or used as new optimized reagents in various combinations with new formulations.

Mittel mit RNasen sind geeignet Gegenstände, wie zum Beispiel Geräte und Kleidung von kontaminierenden RNA-Viren zu reinigen und zu desinfizieren. Agents with RNases are suitable for cleaning and disinfecting objects, such as equipment and clothing, from contaminating RNA viruses.

Mittel mit RNasen appliziert auf Gegenstände und vor allem auf die Hautoberfläche eignen sich als Schutz (Prävention) für Mensch und/oder Tier vor krankheitserregenden RNA-Viren. Agents with RNases applied to objects and especially to the skin surface are suitable as protection (prevention) for humans and / or animals against pathogenic RNA viruses.

Mittel mit RNasen können auch zur Bekämpfung von RNA-Viren im Pflanzenschutz angewendet werden. Agents with RNases can also be used to control RNA viruses in crop protection.

bi Eigenschaften von RNasen am Beispiel RNase A: bi properties of RNases using the example of RNase A:

- Stabilität: hitzestabil (volle Aktivität auch nach kochen!) und trockenstabil - Stability: heat stable (full activity even after cooking!) And dry stable

- Aktivität: wenig beeinflusst vom pH (5-8 optimal), von Salzkonzentrationen (0.3 Mol/I NaCl Optimum) und von Detergentien (z.B. SLS= Sodium Lauryl Sulphate). - Activity: little influenced by pH (5-8 optimal), salt concentrations (0.3 mol / I NaCl Optimum) and detergents (e.g. SLS = Sodium Lauryl Sulphate).

ci Effekt von RNase und Detergentien auf RNA-Viren: ci Effect of RNase and Detergents on RNA Viruses:

- RNA-Viren sind aufgebaut aus ihrer Erbsubstanz RNA und einem Gerüstmantel (=Kapsid) aus Proteinen. Gewisse RNA-Viren besitzen auch eine Membranhülle bestehend aus Lipiden und Proteinen. - RNA viruses are made up of their genetic material RNA and a framework (= capsid) made of proteins. Certain RNA viruses also have a membrane envelope consisting of lipids and proteins.

- Mit geeigneten Detergentien wird die Membranhülle aufgelöst und der Gerüstmantel aufgebrochen, so dass RNasen die Erbsubstanz der RNA-Viren zersetzen können, was zu einer vollständigen Vernichtung der RNA-Viren führt. Damit werden nicht nur Aufnahmefähigkeit durch den Organismus, sondern auch jegliches Vermehrungspotential der RNA-Viren vollständig eliminiert. Diese neuartige Vernichtung der Erbsubstanz RNA zur Inaktivierung scheint sogar wichtig zu sein, da kürzlich gezeigt wurde, dass zum Beispiel Polio-Viren sich allein mit ihrer RNA in intakten oder sogar in aufgelösten Zellen noch vermehren (Science News, Vol. 140, p. 390, 1991). - With suitable detergents, the membrane shell is broken up and the scaffold is broken open so that RNases can break down the genetic material of the RNA virus, which leads to a complete destruction of the RNA virus. This completely eliminates not only the ability of the organism to absorb, but also any potential for multiplication of the RNA viruses. This novel destruction of the genetic material RNA for inactivation even seems to be important, since it has recently been shown that, for example, polio viruses alone multiply with their RNA in intact or even in dissolved cells (Science News, Vol. 140, p. 390 , 1991).

dì Mittel mit RNasen: dì means with RNases:

RNasen können mit verschiedensten herkömmlichen flüssigen oder getrockneten Substanzen zur Reinigung, Desinfektion oder Körperpflege kombiniert oder als neue optimierte Reagentien in verschiedenen Kombinationen mit neuen Formulierungen angewendet werden: RNases can be combined with a wide variety of conventional liquid or dried substances for cleaning, disinfection or personal care or used as new optimized reagents in various combinations with new formulations:

- Zur Reinigung und Desinfektion braucht es mindestens eine RNase und ein Detergens (optimal z.B. Sodium Lauryl Sulfate). Von der Grundlagenforschung ist bekannt, dass RNasen unter verschiedensten Bedingungen wirkungsvoll arbeiten. - For cleaning and disinfection at least one RNase and a detergent (optimal e.g. sodium lauryl sulfate) are required. It is known from basic research that RNases work effectively under various conditions.

- Für den Schutz vor Infektion eignen sich Mittel mit RNase in allen Körperpflegemitteln, wie zum Beispiel Waschlotions, Cremes, Haar-Shampoos, Dusch-Gels, Puders, etc. Je nach Zusammensetzung wirken diese Mittel kurzfristig inaktivierend auf RNA-Viren oder vermitteln eine länger anhaltende Inakti-vierungsfähigkeit auf RNA-Viren. Für eine erwünschte längere protektive Wirkung empfiehlt sich die Anwendung von Mitteln, die einen relativ widerstandsfähigen Film auf den behandelten Oberflächen (Geräte, Kleider, Haut) hinterlassen. Solche Mittel, basierend auf Gelen, Ölen oder Wachsen sind schon zum Teil patentiert und werden in der Praxis angewendet. - To protect against infection, agents with RNase are suitable in all personal care products, such as washing lotions, creams, hair shampoos, shower gels, powders, etc. Depending on their composition, these agents have a short-term inactivating effect on RNA viruses or mediate a longer one persistent inactivation ability on RNA viruses. For a desired longer protective effect, the use of agents that leave a relatively resistant film on the treated surfaces (devices, clothes, skin) is recommended. Such agents, based on gels, oils or waxes, have already been patented in part and are used in practice.

ei Anwenriunn von Mittel mit RNasen: An application of means with RNases:

- Im Pflanzenschutz zur Desinfektion von kontaminierten Geräten und vor allem als Schutzmöglichkeit in Form von widerstandsfähigen protektiven Filmen (Wachse oder Öle) zusammen mit anderen Pflanzenschutzmittel. - In crop protection for the disinfection of contaminated devices and above all as a protection option in the form of resistant protective films (waxes or oils) together with other crop protection products.

- Bei Tieren zur Desinfektion der Geräte, Hausungen und der Tiere selber. - For animals to disinfect the devices, housings and the animals themselves.

- Beim Menschen zur Reinigung und Desinfektion von kontaminierten Geräten, Oberflächen, Kleidung oder sogar der Körperoberfläche (Haut und Schleimhäute). Vor allem für Orte mit grossem Risiko (Spitäler, Labors, Arztpraxen, Lebensräume von RNA-Viren ausscheidenden Personen,...) aber auch zur generellen Prävention drängt sich der Einsatz dieser Mittel mit RNase auf. Der Gebrauch für den Schutz von Personen durch einen «Schutzfilm» ist vor allem zu empfehlen für speziell gefährdete Risikogruppen (z.B. Ärzte, Pflegepersonal, Reinigungspersonal, ...), die mit grosser Wahrscheinlichkeit in Kontakt mit RNA-Viren ausscheidenden Personen oder möglicherweise kontaminierten Gegenständen kommen. - In humans for cleaning and disinfecting contaminated devices, surfaces, clothing or even the body surface (skin and mucous membranes). Above all for places with a high risk (hospitals, laboratories, doctor's surgeries, habitats of people who excrete RNA viruses, ...) but also for general prevention, the use of these agents with RNase is imperative. The use for the protection of people through a «protective film» is especially recommended for especially vulnerable risk groups (e.g. doctors, nursing staff, cleaning staff, ...) who are very likely to come into contact with people who excrete RNA viruses or possibly contaminated objects come.

Im Zusammenhang mit den AIDS auslösenden HIV-RNA-Viren ist ein Schutz der betroffenen Risikogruppen angebracht. Zu gebräuchlichen äusserlichen Kontrazeptiva können Mittel mit RNase zugegeben werden. Condome als momentan bestwirksamer Schutz vor Übertragung von HIV-RNA-Viren können mit einem RNase enthaltenden Schutzfilm beschichtet werden oder zu Gleitmitteln beigefügt werden. Mittel mit RNasen können zudem mit herkömmlichen Gleit-, Massage- oder allgemein mit Körperpflegemitteln kombiniert werden. Protection of the affected risk groups is appropriate in connection with the AIDS-causing HIV-RNA viruses. RNase agents can be added to common external contraceptives. Condoms, as currently the best effective protection against transmission of HIV-RNA viruses, can be coated with a protective film containing RNase or added to lubricants. Agents with RNases can also be combined with conventional lubricants, massage or generally with personal care products.

Da diese Mittel alle die Wahrscheinlichkeit und somit das Risiko einer Infektion mit RNA-Viren vermindern, kann man sie als «anti-infektiva für RNA-Viren» (= aiRVi) bezeichnen. Since these agents all reduce the probability and thus the risk of infection with RNA viruses, they can be described as "anti-infectives for RNA viruses" (= aiRVi).
