| Abstract |
A number of 2-((4-ethylphenoxy)methyl)-N-(substituted-phenylcarbamothioyl) benzamides (1a-h) were synthesized via reaction of 2-((4-ethylphenoxy)methyl)benzoyl isothiocyanate (2) as a key intermediate with several substituted primary aromatic amines. The new compounds were characterized by proton nuclear magnetic resonance ((1)H-NMR), carbon-13 nuclear magnetic resonance ((13)C-NMR), infrared spectrometry (IR), mass spectrometry (MS), and elemental analysis. The anti-inflammatory activity of 1a-h was investigated by acute carrageenan-induced paw edema in mice using the reference drug indomethacin. The results obtained indicated that, of the derivatives developed, 1a and 1d-h exhibited significantly higher anti-inflammatory activity (26.81%-61.45%) when compared with the reference drug indomethacin (22.43%) (P = 0.0490 for 1a, 0.0015 for 1d, 0.0330 for 1f, and P < 0.001 for 1e and 1h). Moreover, the ulcer incidence of 20% for 1e and 1h was clearly lower when compared with the indomethacin group (in which the ulcer incidence was 80%). Of particular note, the ulcer index of 0.2 for 1e was significantly less than that in the indomethacin group (0.6, P = 0.014). Additionally, prostaglandin E2 (PGE2) inhibitory properties were found to be high with 1e (68.32 pg/mL), significantly different from those of the placebo group (530.13 pg/mL, P < 0.001), and equipotent to the effect observed in the indomethacin-pretreated group (96.13 pg/mL, P > 0.05). Moreover, the PGE2 level of 54.15 pg/mL with 1h was also significantly different from that of the placebo group (P < 0.001) and of the indomethacin group (P < 0.05). The significant inhibition of PGE2 observed with 1e (68.32 pg/mL) and 1h (54.15 pg/mL) agree with their observed ulcer incidences. Our overall findings for N-phenylcarbamothioylbenzamides 1a-h clearly suggest that the compounds exhibit an anti-inflammatory effect, potently inhibit PGE2 synthesis, and markedly demonstrate low ulcer incidence. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 August 2013.
All research outputs
#22,759,452
of 25,374,647 outputs
Outputs from Drug Design, Development and Therapy
#1,754
of 2,268 outputs
Outputs of similar age
#187,161
of 210,076 outputs
Outputs of similar age from Drug Design, Development and Therapy
#35
of 43 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,268 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 210,076 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
