[求助] 求翻译一段论文

Thiazole is a heterocyclic organic compound that has a fivemembered
molecular ring structure with molecular formula
C3H3NS. It possesses both an electron-donating group (-S-) and an
electron-accepting group (C]N). It is a stable heterocyclic compound
and has Bird IA value of 79. Thiazole is aromatic on the basis
of delocalization of a lone pair of electrons from the sulphur atom
completing the desirable 6 p electrons to fulfil Huckel's rule. The
thiazole ring is present in many natural and synthetic products
with a broad range of biological activities for example, thiazole
containing vitamin B1 (thiamine) helps in the normal functioning of
the nervous system by its role in the synthesis of acetylcholine [1].
Thiazole ring is highly reactive due to the presence of an acidic
proton at C-2 and has emerged as an important synthon to generate
variety of NCEs (New Chemical Entities). Diverse modifications of
the thiazole ring at various positions led to a variety of novel
compounds with wide spectrum of pharmacological activities such
as antioxidant, antibacterial, antifungal, antitubercular, diuretic,
anti-inflammatory and anticancer activities
