摘要:
Certain novel substituted (5,6)-dihydroanthracenyl compounds of the general formula ##STR1## wherein A, n, p, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are as defined in the specification exhibit retinoid-like properties and are particularly useful in the prevention of post-surgical adhesions.
摘要:
There are disclosed novel processes for producing 2',3'-dideoxy-2'3'-didehydronucleosides, for example, 2',3'-dideoxy-2',3'-didehydrothymidine in high yields and on a large scale. The compounds so-produced are useful as antiviral agents, especially as agents effective against the human immunodeficiency viruses (HIV).
