摘要:
Die vorliegende Erfindung betrifft ein Verfahren zur chromatographischen Trennung von Ectoin aus einem Gemisch, enthaltend Ectoin und Hydroxyectoin, dadurch gekennzeichnet, dass die Trennung mit einer lonenaustauschersäule durchgeführt wird, die ein Verhältnis von Durchmesser zu Höhe von 1 : 8 bis 1 : 20 besitzt. Durch dieses Verfahren wird eine ausgezeichnete Trennung von Ectoin erhalten, ohne dass es zu unerwünschten Verunreinigungen mit erheblichen Mengen an Hydroxyectoin kommt.

摘要:
Substituted heterocyclic compounds are disclosed. The compounds are useful for treating multidrug resistance. The compounds can be formulated in compositions with a carrier and, optionally, a therapeutic agent. One suitable substituted heterocyclic compound has formula (I).
摘要:
The invention relates a method for separating and isolating in a highly purified manner low molecular, similar structured compounds, particularly tetrahydropyrimidine derivatives, for example, 1,4,5,6-tetrahydro-2-methyl-4-pyrimidane carboxylic acids (ectoines) or firoines ( alpha mannosylglycerate, alpha mannosylglyceramide) and the fission products thereof. The fission products are separated with the aid of a pure alcoholic or aqueous solution or mixtures thereof in at least one method of separation and are separated, in particular, in at least two identical or different methods of separation.
摘要:
There is provided cyclic amidine compounds of the following formula (I) wherein: A and A are hydrogen atom, optionally substituted alkyl group; optionally substituted aryl group; or optionally substituted heterocyclic group; and X is -C(R ,R )-C(R ,R )-, -C(R )=C(R )-, -C(R ,R )-C(R ,R )-C(R ,R )-, or -C(R ,R )-C(R ,R )-NH- (wherein, R , R , R , R , R , R , R , R , R , R , R R , R , R , R and R are hydrogen atom; halogen atom; optionally substituted alkyl group; optionally substituted aryl group; or optionally substituted heterocyclic group;or pharmaceutically acceptable salts thereof. These compounds have good affinity for alpha 4 beta 2 nicotinic acetylcholine receptors and activate the same to thereby exert a preventive or therapeutic effect on cerebral dysfunction.
摘要:
The present invention relates to compounds of formula (I), wherein A , A , R , R , R , X and n are as defined in the claims, which are valuable pharmaceutically active compounds for the therapy and prophylaxis of diseases, for example of cardiovascular diseases such as hypertension, angina pectoris, cardiac insufficiency, thromboses or atherosclerosis. The compounds of formula (I) are capable of modulating the body's production of cyclic guanosine monophosphate (cGMP) and are generally suitable for the therapy and prophylaxis of diseases which are associated with a disturbed cGMP balance. The invention furthermore relates to processes for preparing compounds of formula (I), to their use for the therapy and prophylaxis of the abovementioned diseases and for preparing pharmaceuticals for this purpose, and to pharmaceutical preparations which comprise compounds of formula (I).
