摘要:
A synthetic gene characterised in that it codes for the expression of urogastrone or a sub-unit thereof is disclosed.The production thereof by the assembly and ligation of a number of nucleotide blocks is also disclosed, as are corresponding plasmid recombinants, transformed cells and the production thereof.The expression of urogastrone is further disclosed.Urogastrone is a polypeptide hormore (protein) which may be isolated in small amounts from human urine. It has an application in the treatment of ulcers and in the promotion of wound healing. The present invention provides a more viable commercial production.

##STR1## Tri-aza macrocycles of formula (I), wherein m and n, which may be the same or different, is each zero or an integer 1, 2, or 3; p is zero or an integer 1 or 2; q is zero or an integer from 1 to 6 inclusive; R 1 , R 2 and R 3 , which may be the same or different, is each a hydrogen atom or a group --CO 2 H or --P(O)(XH)R 4 (where X is an oxygen or sulpher atom and R 4 is a hydrogen atom or an alkyl or alkoxy group), with the proviso that at least one of R 1 , R 2 and R 3 is a --P(O)(XH)R 4 group; L is a covalent bond or a linker group; Z is a hydrogen atom or a reactive functional group; and metal complexes and/or salts thereof; are described together with processes for their preparation and compositions containing them. The compounds are useful as imaging agents, and in the treatment of abnormal cell disorders, such as in the treatment of tumours, and may be coupled to other molecules, such as proteins, for use in diagnosis and therapy.

The compounds are useful for imaging and in the treatment of abnormal cell disorders, such as in the treatment of tumours, and may be coupled to other molecules, such as proteins for use in diagnosis and therapy.
摘要:
Cross-linking reagents which are highly specific for sulphydryl groups and react with thiols at an excellent rate. The essential feature of the reagents is at least one vinyl group conjugated with an armoatic nitrogen heterocycle. Particular examples include vinyl pyridines, vinyl pyrimidines and vinyl triazines.
