摘要:
A means and method for treating malaria, schistosomiasis, and cancer using a spiro or dispiro 1,2,4-trioxolane is described. The preferred 1,2,4-trioxolanes include a spiroadamantane group on one side of the trioxolane group, and a spirocyclohexyl on the other side of the trioxolane group, whereby the spirocyclohexyl ring is preferably substituted at the 4-position. In comparison to artemisinin semisynthetic derivatives, the compounds of this invention are structurally simple, easy to synthesize, non-toxic, and potent against malarial parasites.

The preferred 1,2,4-trioxolanes include a spiroadamantane group on one side of the trioxolane group, and a spirocyclohexyl or spiropiperidyl ring on the other side of the trioxolane group, whereby the spirocyclohexyl ring is preferably functionalized or substituted at the 4-position or a spiropiperidyl ring that is functionalized or substituted at the nitrogen atom. In comparison to artemisinin semisynthetic derivatives, the compounds of this invention are structurally simple, easy to synthesize, non-toxic, and potent against malarial parasites.

摘要:
Creatine oral supplementation using creatine hydrochloride salt, that may be added to a liquid or other beverage, or may be also used as an additive to solid oral dosages, or as a supplement, and which may be consumed by the athlete, or other party looking for immediate supplementation of strength, and may be added as a supplement within feed to livestock, in the veterinary area.
摘要:
The present invention describes a method for providing creatine to an animal, which includes receiving a creatine ester by the animal. The creatine ester is suitable for being modified by the animal to form creatine.
摘要:
The present invention is directed to a third generation form of creatine, specifically a creatine hydrochloride salt, that drives significant improvements in muscle development and recovery due to its enhanced bio-availability, while causing fewer negative side effects compared to previous forms of creatine.
摘要:
The present invention relates to new bisquinolines useful in the treatment of malaria and to processes for the production thereof. The invention also relates to methods for the treatment of malaria and, in particular, to the treatment of chloroquine-resistant strains of malaria. The compounds of the invention have the following formula: ##STR1## wherein R is a bivalent radical derived from an acyclic or cyclic hydrocarbon by removal of one hydrogen atom from each of two different carbon atoms. R' is hydrogen or lower alkyl (generally containing between about 1 and about 4 carbon atoms). X is hydrogen (--H), fluoro (--F), chloro (--Cl), bromo (--Br), trifluoromethyl (--CF.sub.3), cyano (--CN), or methylsulfoxide (--SOCH.sub.3). In its acyclic form, R generally contains at least two, and no more than about 12, carbon atoms and, preferably, is an unsubstituted straight or branched alkane. In its cyclic form, R contains at least three and, generally, no more than about eight carbon atoms and, preferably, is an unsubstituted cycloalkane. In a preferred embodiment, this invention relates to N,N-bis(7-chloroquinolin-4-yl)alkane diamines which are active against chloroquine-resistant malaria.The bisquinolines of this invention are useful agents against chloroquine-resistant malaria. .+-.-Trans-N.sup.1,N.sup.2 -Bis(7-chloro-quinolin-4-yl)cyclohexane-1,2-diamine is highly preferred for treatment of chloroquine-resistant malaria. This compound is one of the most potent antimalarials discovered to date and is clearly unique in its in vivo activity -80% and 100% cure rates being achieved at doses of 160 and 320 mg/kg, respectively.
