The invention provides adenosine analog compounds that act at P2Y receptors, e.g., the P2Y
2
receptor, including pharmaceutical compositions; and uses thereof to treat or prevent diseases associated with that receptor, e.g., disorders relating to mucus secretion, such as cystic fibrosis, chronic obstructive pulmonary disorder (COPD), asthma, constipation, chronic idiopathic constipation, dry mouth (xerostomia), gum disease, and gastrointestinal problems caused by radiation and chemotherapy for cancer.
The invention relates to a method of detecting and/or assaying nucleoside hydrolases or nucleoside phosphorylases using a chromogenic substrate. Preferred chromogenic substrates have formula (I) where X is OH, or H, and Y is the residue of Y—OH where Y—OH is a chromophore or a compound readily converted to a chromophore and the substrates are hydrolysed by the nucleoside hydrolase to yield ribose or 2-deoxyribose plus Y—OH. Alternatively those substrates may be phosphorylysed by nucleoside phosphorylase to yield ribose-1-phosphate plus Y—OH. The methods may be used to detect and/or assay parasites in biological samples.
