“…Mechanism studies indicate that 4 exerts antiproliferative effects by inhibition of tubulin assembly, with 3-fold greater potency than CA-4, and these data, together with data obtained with compound 5 recently identified by Mohamed et al [64], confirm that the 3 ,4 ,5 -trimethoxyphenyl ring located at the 7-position of the triazolopyrimidine system contributes to maximal activity. This latter derivative, as an analogue of 4 where the aryl ring was moved from the 2-to the 5-position of the 7-(3 ,4 ,5 -trimethoxyphenyl) triazolopyrimidine scaffold and replaced by an amino group, exhibits significant antiproliferative activity (IC 50 : 0.53 µM) against the HCT-116 cancer cell line, with four-fold less activity than CA-4 as a tubulin polymerization inhibitor (IC 50 : 3.84 and 1.1 µM, respectively) [64].…”

“…The [1,2,4]triazolo [1,5-a]pyrimidine scaffold incorporating the 1,2,4-triazole nucleus (Figure 1) was previously identified by us and others as a promising nucleus for the design of new microtubule-destabilizing agents [61][62][63][64][65]. Two different series of compounds that retain the 3,4,5-trimethoxyphenyl ring at the 7-position of the triazolopyrimidine core variably functionalized at its 2-position were evaluated for their antitumor activity [62][63][64].…”

“…In the last decade, many trimethoxyphenyl-based structures were designed, developed, and synthesized as promising anticancer agents that could target tubulin protein, and some of these compounds reached clinical trials, or were approved by the FDA for cancer treatment [ 123 , 124 , 125 ]. Starting with CA-4P ( Figure 1 ), which was approved for thyroid cancer, many other trimethoxyphenyl-based compounds entered the clinical trials for specific cancer types including St.56 (BNC-105p; Figure 11 ), which was found to have considerable potency and an inhibitory effect against the growth of different kinds of cancer cell lines with a broader therapeutic index than CA-4P in vivo.…”

“…[ 1 , 2 , 4 ]Triazolo[1,5- a ]pyrimidine, as an important class of bicyclic N -heteroarenes, exhibits versatile bioactivities, such as antibacterial [ 1 , 2 , 3 ], antiviral [ 4 , 5 , 6 ] and anticancer activities [ 7 , 8 , 9 , 10 , 11 , 12 ]. Recently, [ 1 , 2 , 4 ]triazolo[1,5- a ]pyrimidine derivatives as anticancer agents via acting on different targets, such as tubulin [ 9 , 10 , 11 , 13 , 14 ], LSD1 [ 15 , 16 ] and CDK2 [ 17 ], have aroused remarkable research attention and exhibited potent antitumor activities. 5-Phenyl-[ 1 , 2 , 4 ]triazolo[1,5- a ]pyrimidine 1 as a cytotoxic agent effectively inhibited the growth of MCF-7 cells, with an IC 50 value of 3.91 μM [ 7 ].…”

“…5-Phenyl-[ 1 , 2 , 4 ]triazolo[1,5- a ]pyrimidine 1 as a cytotoxic agent effectively inhibited the growth of MCF-7 cells, with an IC 50 value of 3.91 μM [ 7 ]. As a tubulin polymerization inhibitor, compound 2 showed significant antiproliferative activity against HCT-116 cells, with an IC 50 value of 0.53 μM, and compound 2 could induce cell apoptosis and G2/M phase arrest in HCT-116 cells [ 9 ]. Compound 3 could potently inhibit the polymerization of tubulin (IC 50 = 3.84 μM) and display significant inhibitory potency on T47D, HCT29 and A549 cells (IC 50 = 3.49, 0.24 and 6.05 μM, respectively) [ 11 ].…”
