Insulin derivatives having an extremely delayed time-action profile

a time-action profile and insulin technology, applied in the field of insulin analogues, can solve the problems of poor control of blood glucose, serious shortening of life expectancy, and none of the slow insulin described to date shows the pharmacokinetic properties of an ideal basal insulin,

Problems solved by technology

The disorder may result in a serious shortening of life expectancy.
However—despite the therapeutic advantages already achieved—none of the slow insulins described to date shows the pharmacokinetic properties of an ideal basal insulin.
Clinicians report that the injection phobia present in many people deters them from starting insulin therapy in good time.
As a consequence, the control of blood glucose is poor, leading to the late sequelae of diabetes.

Preparation of the Vector Derivative pINT3580 which Codes for Gly (A21)-Insulin and a Modified C Peptide which Carries Arg Arg at the C / A Chain Boundary

[0083]European patent application EP-A 1 222 207 describes the plasmids pINT358d, pINT91d and the primer sequence Tir. DNA of these products is used to construct the plasmid pINT3580. The plasmid pINT358d is moreover characterized by a gene sequence which codes for a modified C peptide having particular properties. Three primer sequences are synthesized:

[0084]

pint3580_glya21rev(SEQ ID NO: 3)5′-CAAAGGTCGACTATTAGCCGCAGTAGTTCTCCAGCTGG-3′

[0085]This primer serves after working up to introduce glycine (bold print, underlined) instead of asparagine in position 21 of the A chain of the proinsulin sequence encoded by pINT358d.

[0086]

arg_cjuncf(SEQ ID NO: 4)5′-GTCCCTGCAGCGTCGCGGCATCGTGGAGCAG-3′

[0087]This primer serves like the primer arg_cjunc_rev for introducing arginine instead of lysine at the insulin A / B chain boundary.

Construction of the Plasmid pINT3581 Coding for His (A8), Gly (A21)-Preproinsulin

[0092]The construction takes place as described in example 1 by 3 polymerase chain reactions. The product of the third reaction is inserted after Nco1 / Sal1 cleavage into the Nco1 / Sal1-opened pINT91d vector DNA. The primers Tir and pint3580_glya21rev are used. Two further primers are synthesized:

[0094]The codon which codes for histidine in position 8 of the A chain is emphasized by emboldening in each case. The construction is carried out as described in example 1. Template for PCR1 and 2 is DNA of the plasmid pINT3580. PCR1 is carried out with the primer pair Tir / pint3580_Ha8rev and PCR2 is carried out with the primer pair pint3580_Ha8f / pint3580_glya21rev. With the primer pair Tir / pint3580_glya21rev is employed in PCR 3. Template in this case is a mixture of the ...

Construction of the Plasmid pINT3582 Coding for His (A8), Glu (A5), Gly (A21)-Preproinsulin

[0097]The construction takes place as described in example 1 and 2 by 3 polymerase chain reactions. The product of the third reaction is inserted after Nco1 / Sal1 cleavage into the Nco1 / Sal1-opened pINT91d vector DNA. The primers Tir and pint3580_glya21rev are used. Two further primers are synthesized.

[0099]The codon which codes for glutamic acid in position 5 of the A chain is emphasized by emboldening in each case. The construction is carried out as described in example 1. Template is DNA of the plasmid pINT3581. Correct plasmids are called pINT3582.

[0100]The preproinsulin encoded by the plasmid is precursor for the compound YKL202-1, which is characterized as Arg (A0), Glu (A5), His (A8), Gly (A21), Arg (B31), Arg (B32)-NH2-human insulin, and which results...

Abstract

The invention relates to novel insulin analogs having a basal time-action profile, which are characterized by the addition and / or substitution of negatively and positively charged amino acid residues and by an amidation of the C-terminal carboxy group of the B chain and histidine in position 8 of the insulin A chain. The invention also relates to the production and use thereof.
