Monofunctional alkylating chemotherapeutic agents from the triazene family, dacarbazine (Souliotis et al. 1991), procarbazine (Souliotis et al. 1990), temozolomide (Taverna et al. 1992 - study done in mice) and streptozotocin (Bennett and Pegg 1981 - study done in rats), produce DNA damage in the form of O6-methylguanine (O6meG), which can be reversed by MGMT (6-O-methylguanine-DNA methyltransferase).
