A series of novel naphthalimide dithiocarbamate 4a-f, 5a-f were efficiently synthesized via introduce dithiocarbamate and dithioate side chain onto the naphthalic anhydride core. The structures of the synthesized analogs were elucidated by spectroscopic methods, including IR,1H and 13C NMR, and (ESIHRMS) techniques. The anti-cancer activities of the generated naphthalimide derivatives 4c, 4d, 4e, 4f, and 5d were evaluated against 21 tumour cell lines; inculding 10 tumor subpanels using MTT assay. Analogue 4c offer antitumor activity with an IC50 of 10.54 μM against SKBR3 breast cancer cells. Compound 4d showed varying degrees of antitumor activities towards several tumour cell lines ranging from 21.1 to 71.7 μM. In addition to the antitumor activities; the synthesized compounds were evaluated for their In vitro anti-inflammatory activity. Compounds 4c and 4d revealed potent anti-inflammatory properties in comparison with the reference drug celecoxib. Molecular docking studies provided complementary theoretical support for experimental biological data.
