not selective. 1 and 2 had good activity against MCF7, some with lower IC50 than 5-FU. Complexes with X = Br or I had moderate activity against Caco-2 and HepG2, but those with Cl were inactive. Antibacterial activities of 1a, 2b, 3a, and 7 were tested against antibacterial susceptible and resistant Gram-negative and -positive bacteria. 1a, 2b, and 3a showed activity against methicillin-resistant S
