The thiophene ring in the 2-position of the pyrimidine core was shown to have little effect on the interaction of the compound with IN, and so this position was chosen for more dramatic changes influencing the physiochemical properties of inhibitors.

Surface Forms
Morphology
pyrimidine = pyrimidin + ine
A technical chemical name built from specialized combining forms (e.g. 'pyrimidin-') plus the suffix '-ine', so an average B1 learner cannot derive the meaning from familiar English components.
Etymology
Pyrimidine comes from an older chemical name pyridine plus the common ending -ine, and a helpful way to remember it is to notice the pyr- part (as in pyramid) which gives a short, clear image. Pyrimidines are the 'single-ring' building blocks of DNA and RNA, so the name helps you remember they are the smaller, one-ring bases compared with the two-ring purine bases.
