Telavancin
Telavancin is a semi-synthetic derivative of vanocymycin that has bactericidal activity against Methicillin-resistant Staphylococcus aureus (MRSA) and other gram-positive bacteria.  MRSA is an important pathogen capable of causing hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and skin and subcutaneous tissue infections among others.
