Annona species have been a valuable source of anti-infective and anticancer agents. However, only limited evaluations of their alkaloids have been carried out. This review collates and evaluates the biological data from extracts and purified isolates for their anti-infective and anti-cancer activities. An isoquinoline backbone is a major structural alkaloid moiety of the Annona genus, and more than 83 alkaloids have been isolated from this genus alone. Crude extracts of Annona genus are reported with moderate activities against Plasmodium falciparum showing larvicidal activities. However, no pure compounds from the Annona genus were tested against the parasite. The methanol extract of Annona muricata showed apparent antimicrobial activities. The isolated alkaloids from this genus including liriodenine, anonaine, asimilobine showed sensitivity against Staphylococcus epidermidis. Other alkaloids such as (+)-Xylopine and isocoreximine indicated significant anti-cancer activity against A549 and K-562 cell lines, respectively. This review revealed that the alkaloids from Annona genus are rich in structural diversity and pharmacological activities. Further exploration of this genus and their alkaloids has potential for developing novel anti-infective and anticancer drugs.

Endophytic actinomycetes from medicinal plants have been recently reported as the potential producers of antibiotics, anticancer agents and other bioactive compounds. In this study, the distribution and antimicrobial activity of endophytic actinomycetes isolated from Listea cubeba (Lour.) Pers. were investigated. Consequently, the antimicrobial activities of endophytic isolates against eight pathogens, consisting of Salmonella enterica ATCC 14028, Escherichia coli ATCC 11105, Sarcina lutea CNLM, Bacillus cereus ATCC 11778, Proteus vulgaris CNLM, Pseudomonas aeruginosa CNLM, Staphylococcus epidermidis ATCC 12228, Enterobacter aerogenes ATCC 13048 were tested. Total 143 actinomycetes strains were isolated from L. cubeba tissues, in which 53, 23 and 67 strains were respectively obtained from plant samples collected in Thanh Hoa, Hanoi and Phu Tho provinces. Among media used for isolation, the highest number endophytes were from two main media including HV (18.2 %) and SA (16.1 %). Assessment of strains isolated from three kinds of plant tissues, most of endophytes were from roots (n = 65, 45.5 %) and followed by stems (n = 41, 28.7 %) and leaves (n = 37, 25.9 %). Examination of antimicrobial activity of endophytes revealed that 32.9  % of total strains showed inhibitory activity against at least one of the eight tested pathogenic microorganisms. The obtained results indicated that the L. cubeba (Lour.) Pers. could be an extremely rich reservoir for isolation of diverse actinobacteria producing antimicrobial activities and other bioactive compounds.

The present review deals with the progress in medicinal chemistry of spirocyclic compounds, a wider class of natural and synthetic organic molecules, defined as a hybrid of two molecular entities covalently linked via a unique tetrahedral carbon. This spiro central carbon confers to the molecules a tridimensional structurally oriented framework, which is found in many medicinally relevant compounds, a well-known example is the antihypertensive spironolactone. Various bioactive natural products possess the privileged spiro linkage and different chemo-types thereof become synthetically accessible since the 20th century. Actually, there has been a growing interest in the synthesis of heterocyclic hybrids gathered via a spiro carbon. Most of these combinations are two moieties in one scaffold being able to interfere with biological systems through sequential mechanisms. Spirocyclic hybrids containing indole or oxindole units are compounds exhibiting higher interaction with biological receptors by protein inhibition or enzymatic pathways and their recognition as promising anticancer agents in targeted chemotherapy is foreseen. These specific, low-weight and noncomplex spirocyclic hybrids are potent inhibitors of SIRT1, Mdm2–p53 and PLK4, showing affinity for anaplastic lymphoma kinase (ALK) receptor. They are also known as excellent DNA binders, acting on cellular division by arresting the cell cycle at different phases and inducing apoptotic cell death. A structural diversity of spirocyclic hybrids has proved neuroprotective effects, anti-HIV, antiviral and antibacterial activities. Hundred of papers are mentioned in this review underlying chemical issues and pharmacological potencies of spiro compounds, which render them impressive synthetic hits for innovative drug conception.

Rapid tumor growth is dependent on the capability of tumor blood vessels and glycolysis to provide oxygen and nutrients. Tumor hypoxia is a common characteristic of many solid tumors, and it essentially happens when the growth of the tumor exceeds the concomitant angiogenesis. Hypoxia-inducible factor 1 (HIF-1) as the critical transcription factor in hypoxia regulation is activated to adapt to this hypoxia situation. Flavonoids, widely distributed in plants, comprise many polyphenolic secondary metabolites, possessing broadspectrum pharmacological activities, including their potentiality as anticancer agents. Due to their low toxicity, intense efforts have been made for investigating natural flavonoids and their derivatives that can be used as HIF-1α inhibitors for cancer therapy during the past few decades. In this review, we sum up the findings concerning the inhibition of HIF-1α by natural flavonoids in the last few years and propose the idea of designing tumor vascular and glycolytic multi-target inhibitors with HIF-1α as one of the targets.
