Abstract:
1,3-Dihydroxybenzol-Derivate der allgemeinen Formel (I) oder (Ia) oder deren physiologisch verträglichen, wasserlöslichen Salze, mit R'1 gleich einer substituierten Pyridylgruppe, einer Pyrimidylgruppe, einem Rest der Formel (IIa) oder (IIIa), (IIa), (IIIa)sowie diese Verbindungen enthaltende Färbemittel für Keratinfasern.
Abstract:
Novel biphenyl and biphenyl-like cannabinoid compounds are presented. These compounds, when administered in a therapeutically effective amount to an individual or animal, result in a sufficiently high level of that compound in the individual or animal to cause a physiological response. The physiological response useful to treat a number of physiological conditions.
Abstract:
The invention relates to 1,3-dihydroxybenzene derivatives of general formula (I) or (Ia), or the physiologically acceptable, water-soluble salts thereof, R'1 representing a substituted pyridyl group, a pyrimidyl group, or a radical of formula (IIa) or (IIIa). The invention also relates to colorants containing said compounds and used on keratin fibres.
Abstract:
Cytoprotective compounds, many of which are phenolic derivatives characterized by a substituded phenol having certain conjugated bonds, are useful in the treatment of certain ischemic or inflammatory conditions, including but not limited to stroke, myocardial infraction, congestive heart failure, and skin disorders characterized by inflammation or oxidative damage. They are also useful in the manufacture of pharmaceutical and cosmetic formulations for the treatment of such conditions.
Abstract:
Tetracyclic compounds having structure (1) are described, wherein R1-R10 are as defined. The tetracyclic compounds are capable of potent effects on steroid sensitive tissues and have demonstrated increased uterine weight, antiovolatory effects and potent steroid receptor binding. The compounds have therapeutic utility in reproductive applications such as fertility control, labor induction, ovulation induction and spermatogenesis. Methods for preparing the tetracyclic compounds from substituted indanones are also described.

Abstract:
Compounds of formula (I), wherein R5 is an [A]-CH3, -[A]-C(OH)ZZ' or -[A]-C(O)Z" grouping where -[A]- is an alkylene, alkenylene or alkynylene radical or a single bond, and Z, Z' and Z" are a hydrogen atom or an optionally substituted alkyl, alkenyl, alkynyl or aryl radical; and R1, R2, R3, R4, R6, R7 and R8 are as defined in the description; the use thereof as a drug, pharmaceutical compositions containing same, a preparation method therefor, and intermediates of said method, are disclosed.
Abstract:
Disclosed is the use of the reactive components of the inverse electron-demand Diels Alder reaction for chemical masking and unmasking in vitro. This can be applied in complex chemical reactions and, particularly in the synthesis of biomolecules, e.g. on solid supports. The reactice components are a dienophile, particularly a trans-cyclooctene, and a diene, particularly a tetrazine.
Abstract:
Certain disclosed embodiments of the present invention concern a method for making biaryl compounds by combining a diene with a dienophile under reaction conditions that facilitate a Diels-Alder reaction. Certain embodiments are particularly directed to making a tetra-ortho-substituted biaryl compounds. The disclosed method may involve using novel dienes, dienophiles, or both. Similarly, certain of the biaryl compounds are novel compounds too. Additional disclosed embodiments concern a method for making useful compounds by first making a Diels-Alder adduct. The Diels-Alder adduct is then further modified or coupled to other compounds. The method can be used to make carbazoles, such as Siamenol. Disclosed biaryl compounds are useful for a number of applications, such as pharmacophores and organocatalysts.
