Context examples:
The addition of sulfobutyl ether beta-cyclodextrin to the formulation improves the solubility, stability and ease of use of melphalan; cyclodextrins are cyclic dextrins derived from starch.
(Melphalan Hydrochloride/Sulfobutyl Ether Beta-Cyclodextrin Complex, NCI Thesaurus)
This gene plays a role in ligand-dependent cyclic GMP synthesis.
(NPR1 Gene, NCI Thesaurus)
A synthetic long-acting cyclic octapeptide with pharmacologic properties mimicking those of the natural hormone somatostatin.
(Octreotide, NCI Thesaurus)
Activation results in increasing cellular levels of cyclic guanosine monophosphate (cGMP) within vascular smooth muscle, which results in vasodilation mediated by cGMP-dependent protein kinases.
(Pentaerythritol Tetranitrate, NCI Thesaurus)
Subsequent lack of activation of guanylyl cyclase through nitric oxide results in decreased cyclic GMP (cGMP) levels, thereby inhibiting constriction of smooth muscle tissue, and decreased capillary permeability and histamine-activated allergic reactions.
(Pheniramine Maleate, NCI Thesaurus)
Subsequent lack of activation of guanylyl cyclase through nitric oxide results in decreased cyclic GMP levels, thereby inhibiting smooth muscle constriction of various tissues, decreasing capillary permeability and decreasing other histamine-activated allergic reactions.
(Phenyltoloxamine, NCI Thesaurus)
Usually, this refers to cyclic nucleotide phosphodiesterase, an enzyme that breaks the phosphodiester bond in the second messenger molecules cAMP and cGMP.
(Phosphodiesterase Inhibitor, NCI Thesaurus)
This allele, which encodes cGMP-specific 3',5'-cyclic phosphodiesterase protein, is involved in the regulation of second messenger metabolism.
(PDE5A wt Allele, NCI Thesaurus)
This allele, which encodes cAMP-specific 3',5'-cyclic phosphodiesterase 4B protein, is involved in the regulation of second messenger signaling.
(PDE4B wt Allele, NCI Thesaurus)
The acetate salt of a synthetic long-acting cyclic octapeptide with pharmacologic properties mimicking those of the natural hormone somatostatin.
(Octreotide Acetate, NCI Thesaurus)
