Definitions
- VOACAMINE AS ANTI-PALUDEEN AGENT AND ANTI-PALUDEEN AGENT CONTAINING VOACAMINE
- the present invention relates to voacamine and to its use as an anti-malarial agent exhibiting strong activity all against all strains of Plasmodium, whether resistant or not.
- resistant strains is meant strains resistant to quinolitic alkaloids such as quinine and chloroquine, as well as strains resistant to aminocrinodines.
- This alkaloid is known for its cytotoxic activity (J. Nat. Prod., 1994, 57, 1517) and for its anti-bacterial activity both against Gram + bacteria and against Gram - bacteria (Phytochemistry, 1984, 23 1771).
- the object of the present invention is the use of voacamine as an anti-malarial agent, against strains of Plasmodium, in particular of Plasmodium falciparum, including resistant strains.
- Malaria or malaria is a serious endemic disease which affects the populations of tropical and sub-tropical countries and which is carried by a mosquito.
- the parasite is a hematozoan of the genus Plasmodium, for example Plasmodium vivax, Plasmodium ovale, Plasmodium malariae and above all, the most dangerous, Plasmodium falciparum.
- This disease is combated by various drugs which are generally quinolitic alkaloids, such as chloroquine, or aminocrinodines.
- Plasmodiums have gradually developed resistance, especially to chloroquine, and this drug has become ineffective in many parts of the world.
- Other drugs such as aminocrinodines, which unfortunately are toxic, must be substituted.
- the inventors have demonstrated the effectiveness of voacamine against Plasmodium strains, including those which have become resistant to quinolitic alkaloids and to aminocrinodines, and this without any side effect known to date.
- the invention therefore relates, in a first aspect, to voacamine as an anti-malarial agent.
- the invention relates to anti-malarial agents containing voacamine, in particular plant extracts which contain this alkaloid.
- the invention therefore relates to basic extracts of plants of Voacanga, but also to basic extracts of other plants containing voacamine, in particular to basic extracts of plants of the genus Peschiera (or Tabernaemontana), in particular Peschiera van heurckii, Pescheria campestris, Peschiera affinis, Peschiera laeta and more particularly Peschiera Fuchsiaefolia.
- Peschiera Fuchsiaefolia an apocyanced of the subfamily Tabemaemotanoideae, is a plant native to South America, in particular from the Amazon basin. Called in Brazil "leitiero de vaca", it is a weed infesting pastures, which is treated with pesticides. It has recently been reported that extracts from this plant can be used to neutralize cobra venom (J. Venemous Anima Toxins 1997, 3, 22).
- the invention therefore also relates to a basic extract of Peschiera, in particular of Pescheria Fuchsiaefolia and more particularly still an extract basic seeds, stem bark or roots of Peschiera Fuchsiaefolia, rich in tertiary alkaloids.
- Tabernamine, ervahanin A, vobasin, conopharygin, heyneanine, voacristaine and coronaridine were isolated from this plant for the first time.
- voacamine or the basic extract of plants containing voacamine it is possible to manufacture medicaments in which the alkaloid (s) present, in the form of free base or of physiologically acceptable salts, are incorporated in a pharmacologically acceptable carrier or excipient.
- Yet another aspect of the invention is a method of isolating from Peschiera, in particular Pescheria Fuchsiaefolia, a basic extract having anti-malarial properties, as well as a method of isolating voacamine from from these same plants.
- the extract in question can be prepared by treatment with a dilute acid of a dry ground material of Pescheria Fuchsiaefolia or of a part of the plant only.
- the isolation of voacamine from this fraction rich in tertiary alkaloids is carried out by countercurrent distribution between an aqueous phase and an organic phase by varying the pH of the aqueous phase.
- Voacamine as well as the basic extracts containing it, in particular Pescheria Fuchsiaefolia extracts, can be formulated in the form of medicaments, according to conventional galenic techniques, for example in the form of injections, syrups, suppositories, tablets. or tablets, effervescent or not, or capsules.
- pharmacologically acceptable excipients and carriers such as sugar, lactose, etc., will be used.
- voacamine and the alkaloids which may accompany it may be in the form of free bases or physiologically acceptable salts, such as hydrochlorides, etc.
- the starting material is Peschiera Fuchsiaefolia root bark harvested in Brazil, in Porto Alegre, which has been identified locally, botanically, by the Cibecol pharmaceutical industry.
- the various tertiary alkaloids contained in the basic extract of Example 1 are separated by distribution against the current with dichloromethane as stationary phase and an aqueous buffer at decreasing pH in stages (mobile phase).
- the alkaloids are recovered from the aqueous phase by extraction with dichloromethane.
- the apparatus used is a Craig type Post apparatus consisting of 200 glass tubes (volumes of 10 ml for the lower phase and 10 ml for the upper phase).
- K r represents the partition coefficient (water phase / organic phase distribution) and K b is the dissociation constant.
- Each alkaloid is purified by one or more new recycling cycles in a counter-current distribution, then by crystallization.
- the alkaloids were identified by 1 H, 13 C and mass spectrometry.
- the most active is the basic extract of the tertiary alkaloids of Example 1 obtained from the bark of the roots.
- Each of these persons is injected with 4 ml of the basic extract of Example 1 in 100 ml of physiological solution at the level of the 7th, 8th or 13th vertebra.
