Abstract: The present invention relates to a pharmaceutical composition which comprises progestogens, preferably drospirenone, estrogens, preferably ethinylestradiol and 5-methyl-(6S)-tetrahydrofolate, can be employed as oral contraceptive and moreover prevents disorders caused by folate deficiency in the consumers, in particular cardiovascular disorders and, after conception of the embryo, congenital malformations caused by folate deficiency such as, for example, neural tube defects, ventricular valve defects, urogenital defects, and cleft lip, jaw and palate, without masking the symptoms of vitamin B12 deficiency, and at the same time even in the case of homozygous or heterozygous polymorphism of methylenetetrahydrofolate reductase facilitates unimpaired utilizability of the folate component 5-methyl-(6S)-tetrahydrofolate by the body and thus its biological activity for preventing the abovementioned congenital malformations caused by folate deficiency.

Abstract: The present invention is directed towards new trifunctional folate-conjugates comprising a folate, an albumin binder and a radionuclide-based therapeutic or diagnostic moiety as well as pharmaceutical compositions thereof, their method of production and their use in diagnostic and therapeutic medical applications, such as diagnostic nuclear imaging and radionuclide therapy.

Abstract: Method for selective targeting of one or more effector moiety such as diagnostic or a therapeutic agent to a cell or population of cells expressing a folate-receptor comprising simultaneous or sequential administration of an antifolate with a folate- or pteroate-conjugate comprising said one or more effector moiety.

Abstract: This invention relates to stable pharmaceutical compositions of 5,10-methylene-(6R)-, -(6S)-, or -(6R,S)-tetrahydrofolate (MTHF), by adjusting a basic pH and the simultaneous use of citrate. Stabilisation is effected even in the absence of a reducing agent. The present invention is particularly suitable for producing lyophlisation solutions and lyophilisates or dry powders and dry mixtures, since the stable MTHF solutions can be used in high concentrations for filling corresponding vessels such as vials, ampoules, etc. The lyophilisates have a surprisingly long shelf life and are surprisingly stable. They can be reconstituted without problems by adding wateror aqueous solutions, and the final clear injection solutions again exhibit excellent stability properties. Moreover, the present invention even makes it possible to prepare difficulty soluble calcium 15 or acidic salts of MTHF in high concentrations and as physiologically compatible isotonic solutions.
