The operations of these tweezers, however, require either the involvement of enzymes which may be subject to thermodynamic limitations, or rigid pH control of the system which suffers from tedious preparation processes, or the use of toxic azobenzene moieties.
The presence of halogen substituents particularly at the para position of chalcone backbone has been reported with excellent biological activities such as antibacterial [26] and anti-inflammatory [27], while azobenzene bearing aryl/alkyl and N=N reactive moieties have been extensively reported due to its excellent antibacterial [28, 29], antioxidant [30], anti-inflammatory [31], antifungal [32], and antitumor [33] properties.
Screening of this type of compounds has identified small molecules that can specifically inhibit the expression of miRNAs, as azobenzene, which affects miR-21 expression [361], or several molecules that inhibit miR-122 that could be useful for HCV therapy [362].
The absorption band at 3,485 [cm.sup.-1] was associated with the stretching vibration of hydroxyl of carboxylic acid; the absorption band at 2,910-2,500 [cm.sup.-1] was associated with the stretching vibration of association hydroxyl of carboxylic acid; the absorption band at 1,690 [cm.sup.-1] was associated with the stretching vibration of carbonyl; the absorption band at 1,270-1,250 [cm.sup.-1] was associated with the stretching vibration of sulfonic group; and the absorption band at 1,131 [cm.sup.-1] was associated with the stretching vibration of azobenzene groups; the absorption band at 1,238-1,150 [cm.sup.-1] was associated with the stretching vibration of ether linkage.
