A series of novel quinazoline derivatives containing piperazine analogs are synthesized via substitution reactions with 6,7-disubstituted 4-chloroquinazoline and benzyl piperazine (amido piperazine). Potent antiproliferative activities are observed against A549, HepG2, K562, and PC-3 with N-(3-chlorophenyl)-2-(4-(7-methoxy-6-(3-morpholino-propoxy)quinazoline-4-yl)piperazine-1-yl)acetamidename C9 showing excellent activity. This active derivative was screened for cell migration ability, proliferation effects, and apoptosis against A549 and PC-3 cells, with the result showing biological activity almost equal to that of the control gefitinib.

<p>The glycoslated macrocyclic antibiotic fidaxomicin (1, tiacumicin B, lipiarmycin A3) displays good to excellent activity against Gram-positive bacteria and was approved for the treatment of Clostridium difficile infections (CDI). Main limitations of the compound include low water solubility, which impacts further clinical use. We report on the synthesis of new fidaxomicin derivatives based on structural design and utilizing an operationally simple one-step protecting group-free preparative approach from the natural product. An increase in solubility of up to 25-fold with largely retained activity was observed. Furthermore, hybrid antibiotics were prepared that show improved antibiotic activities</p>
