摘要:
Novel oligonucleotide analogs of the formula [I] are described, ##STR1## in which A, B, D, G, L, P, Q, Q', R.sup.5, R.sup.6, X, Y, Z and n are as defined in the description, which have useful physical, biological and pharmacological properties, as well as a process for their preparation. Their application relates to use as inhibitors of gene expression (antisense oligonucleotides, ribozymes, sense oligonucleotides and triplex-forming oligonucleotides), as probes for the detection of nucleic acids and as auxiliaries in molecular biology.

摘要:
The tendamistat gene can be used for the construction of fused genes with which fusion proteins are expressed and excreted in Streptomycetes host cells. The tendamistat portion can be modified, in particular it can be C-terminal shortened. When a gene for a shortened proinsulin in which the insulin B chain is linked to the A chain only via Lys or Lys-Lys is coupled to the tendamistat gene, this gene construction is introduced into an expression vector, and the latter is used to transform a Streptomycetes host cell, there is expression and secretion of the corresponding fusion protein. The fusion protein can easily be cleaved to give insulin precursors because of correctly established disulfide bonds. Genetic structures which code for the signal sequence and about the first ten amino acids of tendamistat as well as a desired protein are expressed in streptomyces host cells with a high yield, and the fusion proteins are secreted into the medium.
