The use of nonsteroidal anti-inflammatory drugs (NSAIDs) dates back to thousands of years when man used natural sources of these agents in a lot of pain and inflammatory conditions. The tone for modern day discovery and use of NSAIDs was set with the discovery of aspirin. Today in addition to aspirin, a host of other NSAIDs of varying potency and efficacy is employed in the management of pain and inflammatory conditions. This chapter looks with key interest in the existing and evolving role of NSAIDs in therapeutics with emphasis on the current insights into their mechanism of action and side effect profiles associated with its use in pain and inflammation as well as its potential therapeutic benefits in cancer chemotherapy.

Plant-derived compounds have been an integral component in man’s quest to discover ideal anticancer agents. A number of new agents are currently in clinical development with promising selective activity against cancer cell lines and cancer-related molecular targets. This book chapter discusses 14 of such compounds isolated from African plants from 15 plant families. Also contained in this book chapter are compounds from African plants that hold prospect as potential anticancer agents as informed by their in vitro and in vivo preclinical studies. It is, therefore, worthwhile that researchers in the African continent and the world over should keep on working on identifying biomolecules with potential in cancer management.

The prevalence of conditions that eventually result in poor wound healing abounds as humans advance in age. With the increased possibility of wounds not healing comes a leap in morbidity and mortality with its accompanying socioeconomic impact. It is therefore relevant to understand what accounts for aberrant wound healing and more importantly the molecular markers involved in this pathological state. There are known events associated with the wound healing process, spanning from cellular involvement to the role of specific proteins such as cytokines and growth factors that are significant biomarkers in the wound healing process. This chapter discusses biomarkers relevant to the wound healing process, and these biomarkers go a long way to help identify and stratify nonhealing patients for whom biomarker-guided approaches may be of importance clinically in their management.

The surge in antimicrobial resistance coupled with the decline in the antimicrobial drug pipeline calls for the discovery and development of new agents to tackle antibiotic resistance and prevent a return to a post-antibiotic era. Several factors account for resistance of microbes; some are natural and others are acquired. Natural selection, presence of efflux pumps, impermeable cell wall, biofilm formation and quorum sensing are some of the factors. Though it is difficult to outwit the pathogens, the discovery and development of compounds with pleiotropic modes or mechanisms of action different from the conventional drugs currently being used can help us tackle antimicrobial resistance. Natural products have been known to be a rich source of bioactive compounds with diverse structures and functional group chirality. Various reports indicate medicinal plants with antibacterial, anti-biofilm, efflux pump inhibition, wound healing effects or properties and others used for upper respiratory and urinary tract infections. There is an urgent need to research into natural products particularly plants for antimicrobial agents including antibacterial agents, anti-biofilm agents, antibacterial natural compounds and antibacterial chemicals. This chapter throws more light on such antimicrobials.
