The Pharmaceutical Inspection Convention and Pharmaceutical Inspection Co-operation Scheme (PIC/S) are two international instruments between countries and pharmaceutical inspection authorities. The PIC/S is meant as an instrument to improve co-operation in the field of Good Manufacturing Practices between regulatory authorities and the ...
Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP.Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface.

Good manufacturing practice guidelines provide guidance for manufacturing, testing, and quality assurance in order to ensure that a manufactured product is safe for human consumption or use. Many countries have legislated that manufacturers follow GMP procedures and create their own GMP guidelines that correspond with their legislation.
In the US, Good Manufacturing Practice (GMP) Regulations are based on the Code of Federal Regulations 21 CFR 210/211, and USP 1079. The US Drug Supply and Chain Security Act (DSCSA), was enacted by Congress on November 26, 2013 and outlines requirements to build electronic systems that identify and trace prescription drugs distributed in the US ...
Once AMP or GMP are formed, they can be phosphorylated by ATP to their diphosphate and triphosphate forms. [23] Purine synthesis is regulated by the allosteric inhibition of IMP formation by the adenine or guanine nucleotides. [24] AMP and GMP also competitively inhibit the formation of their precursors from IMP. [25]
GMP synthase is the second step in the generation of GMP from IMP; the first step occurs when IMP dehydrogenase generates XMP, and then GMP synthetase is able to react with glutamine and ATP to generate GMP. IMP may also be generated into AMP by adenylosuccinate synthetase and then adenylosuccinate lyase.
GAMP itself was founded in 1991 in the United Kingdom to deal with the evolving U.S. Food and Drug Administration expectations for good manufacturing practice (GMP) compliance of manufacturing and related systems. [4] GAMP published its first guidance in 1994.
