Abstract |
: |
The literature survey on heterocyclic compound containing sulfone group and their derivatives revealed that they are endowed with wide variety of biological activities. In this work, new polymers based on 2-bromo-1-(thiophen-3-yl)ethan-1-one (M1) and 2-(phenylsulfonyl)-1-(thiophen-3-yl)ethan-1-one (M2). These two monomers: (M1) contains thiophene ring and (M2) contain thiophene ring and sulfones group in their structure .The free position 2,5 makes this ring have ability to undergo to a one-step oxidative polymerization . The polymerization was run in the present of FeCl3 as an oxidizing reagent. The P1, P2 have been prepared and their composites with cellulose are investigated in terms of their biological activities. All the polymer composites have been evaluated for antibacterial and pathogenic strains . The results shown in this work provide the antibacterial activity and pathogenic strains for each of the following polymers 10C/ 0P1, 8C/2P1, 8C/2 P2, 6C/4P1, 6C/4P2 , 4C/6P1, 6C/4P2, 2C/8P1, 2C/8P2 , 0C/10 P1, and 0C/10 P2. It is quite interesting to note that most of the tested samples were found to be promising biological agents .It has been shown that the samples 8C/2P1, 8C/2P2, 0C/10P1, 0C/10P2, 2C / 8P1, 2C/8P2, 6C/4P1, 6C/4P2, 4C/6P1, 4C/4P2 show antibacterial activity results were encouraging as the tested samples were able to possess growth inhibiting properties against the mycobacterium tested. In contrast, samples such as 10C/ 0P1 and 10C/ 0P2 which meanly consist only of cellulose were negative. |
