    • The present invention relates to a (poly)peptide or a peptidomimetic thereof having the biological activity of Conkunitzin-S1, wherein said (poly)peptide is selected from (a) a polypeptide comprising or having the amino acid sequence of SEQ ID NO: 1; (b) a polypeptide having at least 85% sequence identity to SEQ ID NO:1; or (c) a fragment of a) or b); wherein said (poly)peptide or peptidomimetic specifically modulates the activity of a channel having the activity of a Kv1.7 containing channel, for the treatment or prevention of metabolic diseases or conditions, or secondary diseases or conditions related to said metabolic diseases or conditions. The present invention furthermore relates to a method of screening for (poly)peptides derived from Conkunitzin-S1 suitable for specifically modulating the activity of a channel having the activity of a Kv1.7 containing channel, comprising: (a) altering the amino acid sequence of Conkunitzin-S1 represented by SEQ ID NO: 1 by deleting and/or inserting and/or replacing at least one amino acid; and (b) determining the modulatory effect of the (poly)peptide obtained in step (a) (i) on a channel having the activity of a Kv1.7 containing channel and (ii) on channels, preferably potassium channels, not having the activity of a Kv1.7 containing channel, which are optionally expressed on the same cell as the channel having the activity of a Kv1.7 containing channel; wherein a modulatory effect of the (poly)peptide determined in step (i) that is at least 50% of the modulatory effect of Conkunitzin-S1 indicates that the (poly)peptide re suitable for modulating the activity of said channel having the activity of a Kv1.7 containing channel; and wherein the determination of essentially no modulatory effect in step (ii) indicates that the (poly)peptide is specifically modulating the activity of channels having the activity of a Kv1.7 containing channel.

    • The invention relates to a method for producing (poly-C 2 -C 4 alkylene glycol)-monoacrylic esters and -monomethacrylic esters, and to a method for producing copolymers of such (poly-C 2 -C 4 alkylene glycol)-mono(meth)acrylic esters with acrylic ester or methacrylic ester and to the use of the polymers as liquefying additives in cement-containing preparations. The (poly-C 2 -C 4 alkylene glycol)-monoacrylic esters and -monomethacrylic esters are produced by reacting acrylic anhydride or methacrylic anhydride (referred to in the following as (meth)acrylic anhydride (A)) with at least one OH group-carrying poly-C 2 -C 4 alkylene glycol compound (P) in the presence of a base, said base being selected from the group of basic compounds that have, at 90° C, a solubility in the poly-C 2 -C 4 alkylene glycol compound (P) of not more than 10 g/l, the molar ratio of (meth)acrylic anhydride (A) to compound (P) (molar ratio (A):(P)) being in the range of from 1:1 to 1.095:1, preferably in the range of from 1.005:1 to 1.09:1, especially in the range of from 1.01:1 to 1.085:1 and most preferred in the range of from 1.02:1 to 1.08:1. The production of (meth)acrylic acid with (poly-C 2 -C 4 alkylene glycol)-mono(meth)acrylic esters comprises the following steps: i) production of a (poly-C 2 -C 4 alkylene glycol)mono(meth)acrylic ester by reacting (meth)acrylic anhydride (A) with at least one OH group-carrying poly-C 2 -C 4 alkylene glycol compound (P) in the presence of a base according to the inventive method, and ii) radical copolymerization of the (poly-C 2 -C 4 alkylene glycol)mono(meth)acrylic ester obtained in step i) with acrylic acid and/or methacrylic acid and optionally additional ethylenically unsaturated monomers.
