A series of sulfocoumarin-, coumarin-, and 4-sulfamoylphenyl-bearing indazole-3-carboxamide hybrids were synthesized and investigated as inhibitors of the human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms I and II (cytosolic isozymes), as well as hCA IX and XII (transmembrane, tumor-associated enzymes). Compounds 6 a–g (amide derivatives) and 7 a–h (triazoles) act as “prodrugs”, and their hydrolysis products are the de facto CA inhibitors. These compounds displayed sub-micromolar to high-nanomolar inhibitory activity against hCA isoforms IX and XII, which were recently validated as antitumor drug targets. Moreover, no inhibition of the off-target hCA I and II isoforms was observed. Compounds 8 a–f (another set of triazoles) exhibited nanomolar inhibition against hCA isoforms I, II, IX and XII, among which compounds 8 c, 8 d, and 8 f were found to inhibit the tumor-associated hypoxia-induced hCA isoform IX with Ki values of 1.8, 2.3, and 2.0 nm respectively. Further exploration of these compounds could be useful for the development of novel antitumor agents with selective mechanisms of CA inhibitory action.

A method of performing a bearer path assurance test across a packet-based IP network is provided. The method includes establishing a bearer path across the IP network and performing a bearer path assurance test during call setup before cutting through the call. The method can also include creating a timestamp at the originating office, sending the timestamp from the originating office to a terminating office, sending the timestamp from the terminating office to the originating office, receiving the timestamp at the originating office, and verifying the continuity of the bearer path. The method can also include evaluating round trip delay and packet loss using one or more timestamps.
