    摘要: A new broad-spectrum anti-viral compound for the treatment of viral infections, such as human immune deficiency virus. The compound has general formula (I). Ar and Ar are each either a phenyl group or substituted aromatic group; R is a primary, secondary or tertiary alkyl or alkenyl group, a phenyl or hydrogen; R is an alkyl group, a primary, secondary or tertiary alkyl amino group or hydrogen; and X is C, O, N or S. Preferred compounds include diethylamino-ethyl-2,2-diphenylvalerate and aminoethyl-2,2-diphenylvalerate.

    摘要: There are described liposomogenic UV absorbers, comprising a hydrophilic head group (=Z), a spacer (=W), a UV chromophore (Q) having an absorption in the range from 285 to 400 nm and at least one hydrophobic tail group (=A) of the formula (1), in which A1 and A2, independently of one another, are a hydrophobic radical, Q is a UV chromophore, W is an organic radical, Z1 and Z2, independently of one another, are a hydrophilic radical, n1 and n2, independently of one another, are a number from 0 to 4, n1=n2=0 not being additionally included, p is 1 or 2, q is a number from 0 to 3, r1 is 1 or 2, r2 is 0 or 1, and s1 is a number from 1 to 3. The liposomogenic UV absorbers according to the invention are preferably used as sunscreen agents in cosmetic preparations. They are capable of self-organization into bimolecular layers, and can thereby penetrate into the stratum corneum to a high extent and behave there in an extremely wash-resistant manner.
