From the 80% EtOH extract of Cryptolepis sanguinolenta (Lindl.) Schlechter (Periplocaeae) root bark, a cryptolepine isomer named neocryptolepine, and two dimeric alkaloids named biscryptolepine and cryptoquindoline were isolated. These compounds were tested for their putative antibacterial and
Neocryptolepine is an alkaloid isolated from traditional African herbal medicine Cryptolepis sanguinolenta and its broad spectrum of biological activities have been illuminated in past decades. In this study, neocryptolepine and its derivatives (1-49) were designed and synthesized from economical
Cryptolepine is the main alkaloid of Cryptolepis sanguinolenta (Lindl.) Schlechter, a plant used in traditional medicine in West Africa. The minimal inhibitory concentrations (MICs) of cryptolepine, ethanol and aqueous extracts of Cryptolepis sanguinolenta root were determined for 65 strains of
Dysregulated mitochondrial dynamics and biogenesis have been associated with various pathological conditions including cancers. Here, we assessed the therapeutic effect of cryptolepine, a pharmacologically active alkaloid derived from the roots of Cryptolepis sanguinolenta, on melanoma cell growth.
Plants are one of the most important resources for the discovery of new drugs. The potential of natural compounds as new drug leads is clearly illustrated by the discovery and development of many modern medicines. This is an encouraging factor that drives natural products research in the vegetable
Acanthosicyos naudinianus Acanthosicyos naudininus, Gomphocarpus fruticosus, and Cryptolepis decidua are, according to the knowledge of traditional healers, used in Namibia to treat inflammatory disorders such as pain, fever and skin rashes.Since
In our biological screening of higher plants, an aqueous and an 80% EtOH extract from the root bark of Cryptolepis sanguinolenta showed potent antibacterial, anticomplementary, and moderate antiviral activities, but no antifungal effect could be detected. Bioassay-guided fractionation of the 80%
The ongoing global pandemic caused by the human coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has infected millions of people and claimed hundreds of thousands of lives. The absence of approved therapeutics to combat this disease threatens the health of all persons on

Cryptolepis sanguinolenta is a scrambling thin-stemmed shrub found in Africa. Traditionally in West Africa, it is employed in the treatment of malaria, diarrhea, and respiratory conditions. This review discusses the traditional importance as well as the phytochemical, ethnomedical,
Malaria is one of the life-threatening parasitic diseases that is endemic in tropical areas. The increased prevalence of malaria due to drug resistance leads to a high incidence of mortality. Drug discovery based on natural products and secondary metabolites is considered as alternative approaches
Traditional medicines have contributed greatly over the centuries to the discovery and development of new therapeutic agents and indoloquinoline alkaloids may represent a new class of drug leads. Cryptolepine (5-methyl-5Hindolo[3,2-b]quinoline), neocryptolepine (5-methyl-5H-indolo[2,3-b]quinoline),
