Chapter 2 Cancer Resistance and the Current Drug pipeline
This chapter presents a comprehensive review of resistance mechanisms and/or
resistance-associated changes at the gene or protein levels in cancer cells.
These have been identified in a number of cancers and all classes of currently
approved anticancer drugs have been included as part of this review. In total,
this represents around 60 different anticancer drug classes (based on their
general pharmacological mechanisms of action) and includes approximately 190
individual cancer drugs. This chapter also presents the current cancer drug
pipeline (preclinical through to phase III) by agent, pharmacological
mechanism and development phase and identifies new drug types (i.e. based on
new general pharmacological mechanisms) being developed to target cancer in
new and more effective ways.

Chapter 3 Drug Resistance and Cancer Stem Cells
Chapter 3 presents a review of Cancer Stem cells (CSCs), a subset of cancer
cells in tumours that have been strongly implicated in cancer drug resistance.
This chapter also includes proposed resistance mechanisms associated with

CSC-targeting drug development pipeline and the potential of these cells in
cancer diagnostics.

cytotoxic drug, which could result in the increased expression of a specific
ABC transporter (see green boxes representing drug - gene pairs in which an
ABC transporter was found to be overexpressed in cell lines selected for
resistance to the respective drug). Resistant cells overexpressing a single
ABC transporter often show characteristic cross-resistance to other,
structurally unrelated, drugs (red boxes). The ability of ABC transporters to
alter cell survival, drug transport and/or drug accumulation can be inhibited
or altered by various modulators (yellow boxes). White boxes denote unexplored
or absent drug - gene relationships (Source (Adapted From): Targeting
