to have a role in the treatment of cancer. Several sulfonamide compounds bearing an aromatic or a heteroaromatic ring were found to posses potent carbonic anhydrase inhibitory activity and so can be used in the treatment of several types of cancer. In this paper, we present the synthesis of some novel quinoline 7–13, 21–26, 28 and pyrimidoquinoline 14–18, 20, 27 derivatives having a sulfonamide moiety

Some novel quinolines and pyrimido[4,5-b]quinolines have been synthesized. The structures of which were confirmed by elemental analyses and spectral data. All the target compounds were subjected to in-vitro antitumor activity against Ehrlich Ascites Carcinoma (EAC) cells. Compounds 24, 19 and 12 showed higher activity with IC50 values (5.5, 6.9, 7 μg/ml) when compared with Doxorubicin as a reference

5 μg/mL) are more potent and efficacious than Doxorubicin (CAS-23214-92-8) as reference drug with (IC50 value = 37.5 μg/mL). Also, compounds 28, 30, 31, and 34 (with IC50 values = 25 μg/mL) are nearly as active as Doxorubicin.

Sulfonamide containing molecules are of sound biomedical interest. This work comprises the synthesis and in vitro antitumor testing of new library of 20 such molecules. These compounds were screened for cytotoxic activity against three tumor cell lines MCF-7, HeLa, and HepG2 using MTT assay. The yield was low but all the target compounds exhibited antiproliferative activity better than the standard drug Doxorubicin (CAS-23214-92-8). Seven compounds were more potent and four compounds were as active as the standard drug. There were no great difference between compounds obtained from dimedone and those obtained from cyclohexandione. Also no significant difference found in activity between compounds bearing o-amino ethyl ester side chain and compounds bearing o-amino amide derivatives. However, compounds bearing o-amino-cyano group, although retained considerable activity they were far less active than the preceding two. It was clear that monohydroxy aldehyde derivatives were less active compared with the di and trihydroxy ones.

many types of biological activities and have been recently reported to show substantial antitumor activity in vitro and/or in vivo. There are a variety of mechanisms for the anticancer activity, and the most prominent mechanism is the inhibition of carbonic anhydrase isozymes. This work reports the synthesis of somenewquinoline, pyrimido[4,5‐b]quinoline and 3,1‐oxazinoquinoline derivatives bearing a
