“…The Schiff base reaction occurs when aldehydes (or ketones) combine with amino acids, forming imine groups (C=N). Schiff bases of heterocyclic aldehydes and amino acids containing nitrogen, oxygen, and sulphur atoms are a class of compounds that exhibit significant biological activity [24], including antiviral [25], antifungal [26], antioxidant [27], anti-inflammatory [28], antitumor [29,30], anticancer [31,32], antibacterial [33,34], and antipyretic applications [11,35]. Several biological activities such as cytotoxicity studies, antibacterial, antifungal, anti-tuberculosis, DNA binding, antioxidant, scavenging, and antiviral activities have been performed [36] using isoniazid Schiff bases.…”
