Abstract
Cancer is known to be the second most common disease-related cause of death among humans. In drug discovery programs anti-cancer chemotherapy remains quite challenging due to issues related to resistance. Plants used in traditional medicine are known to contribute significantly within a large proportion of the African population. A survey of the literature has led to the identification of ~400 compounds from African medicinal plants, which have shown anti-cancer, anti-proliferation, anti-tumor and/or cytotoxic activities, tested by in vitro and in vivo assays (from mildly active to very active), mainly alkaloids, terpenoids, flavonoids, coumarins, phenolics, polyacetylates, xanthones, quinones, steroids and lignans. The first part of this review series focuses on xanthones, quinones, steroids, coumarins, phenolics and other compound classes, while part II is focused on alkaloids, terpenoids, flavonoids.
Keywords: Africa, cancer, cytotoxic activities, medicinal plants, traditional medicine.

Advances in Nanomedicines and Targeted Therapies for Colorectal Cancer
Colorectal cancer remains a significant global health challenge, with high incidence and mortality rates despite advancements in treatment strategies. Conventional therapies often face limitations such as systemic toxicity, drug resistance, and suboptimal targeting. The advent of nanomedicines and innovative drug delivery systems offers new hope for overcoming these challenges and ...read more
Discovery of Lead compounds targeting transcriptional regulation
Transcriptional regulation plays key physiological functions in body growth and development. Transcriptional dysregulation is one of the important biomarkers of tumor genesis and progression, which is involved in regulating tumor cell processes such as cell proliferation, differentiation, and apoptosis. Additionally, it plays a pivotal role in angiogenesis and promotes tumor ...read more
Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes that aid in stabilizing chromosomal makeup. The resynthesis of telomeres is supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no telomerase activity in human somatic cells, but the stem cells and germ cells undergo ...read more
