Article Abstract
A new series of 4-(4-aryl-1-piperazinyl)quinazolines 4a-f, 4-(3-substituted phenylamino)quinazoline derivatives 5a-h, 2-methoxycarbonylphenylaminoquinazoline derivatives 6a, b, 2-hydrazinocarbonylphenylaminoquinazolines 7a, b and 2-aryl-1-(substituted 4-quinazolinyl)-1,4-dihydro-5-oxo-5H-1,3,4-benzotriazepines 8a-j have been synthesized and tested for their antitumor and antiviral activities. Among them, compounds 5a-d exhibited broad spectrum antitumor activity with full panel median growth inhibition (GI50) at concentrations of 3.2, 2.0, 4.8, 4.0 mumol/l and total growth inhibition at concentrations of 56.5, 51.0, 63.0 and 73.0 mumol/l, respectively. Compounds 7a and 7b showed moderate selectivity toward leukemia cell line. On the other hand, compounds 8a and 8b showed moderate anti HIV-1 potency with EC50 values of 40.5 and 52.8 mumol/l, respectively. The detailed synthesis, spectroscopic and biological data are reported.

Introduction: Despite the established influence of gut bacteria, the role of the gut virome in modulating colorectal cancer (CRC) patient chemotherapy response remains poorly understood. In this study, we investigated the impact of antiviral (AV) drug-induced gut virome dysbiosis on the efficacy of 5-FU in CRC treatment.
Methods: Using a subcutaneous CRC mouse model, we assessed tumor growth and immune responses following AV treatment, fecal microbiota transplantation (FMT), and 5-FU administration.
