Six new compounds 1–6 and two new naturally occurring compounds 7 and 8, together with nine known compounds 9–14, beauverioride I, dipicolinic acid, and 6-(methoxycarbonyl) picolinic acid were isolated from a wasp-pathogenic fungus Beauveria asiatica, strain BCC 16812. Their structures were determined by extensive spectroscopic analyses. The absolute configurations of compound 6 were established by the application of modified Mosher's method and ECD calculation. Compounds 9–11 exhibited antimalarial (IC50 0.47–1.79 u g/mL), antimicrobial (MIC 3.13–50.0 u g/mL), and cytotoxic (IC50 0.26–1.23 u g/mL) activities, while compounds 1, 2, 8, and 14 showed only cytotoxicity against Vero cell lines, with IC50 values range 12.96–47.03 u g/mL.

Eleven new compounds, including two quinone derivatives of bioxanthracene, conoideocrellones A (1) and B (2), two bioxanthracenes 3 and 4, four isocoumarins and isocoumarin glycosides 7–10, two phenolic compounds 16 and 17, and a diterpenoid compound, conoideocin A (18), were isolated from culture of the scale-insect pathogenic fungus Conoideocrella tenuis BCC 44534. Seventeen known compounds, compounds 5 and 6, ES-242-2 and its atropisomer, isocoumarins and isocoumarin glycosides 11–15, 3,4,6-trihydroxymellein, cis-4,6-dihydroxymellein, metarhizins A (19) and B (20), BR-050 (21), 5α,8α-epidioxy-24(R)-methylcholesta-6,22-dien-3β-ol, zeorin, and conoideocrellide A, were also isolated from this fungus. Structures of these compounds were elucidated by NMR and MS data analyses. Compound 4 was active against Plasmodium falciparum K1 (IC50 6.6 μg/mL), while it did not show cytotoxicity. Conoideocrellone A (1) and compounds 3 and 7 exhibited cytotoxic activity, while conoideocin A (18) showed broad range of biological activities including antimalarial, antibacterial, and cytotoxic activities.

Six new compounds, an N-hydroxypyridone glucoside, orbiocrellin A (1), its aglycone orbiocrellin B (2), chromone glucosides 3 and 4, a dihydrochromone 5a/5b, and a chromone 6, were isolated from the scale-insect pathogenic fungus Orbiocrella sp. BCC 33248. Orbiocrellin A (1) exhibited antimalarial activity against Plasmodium falciparum K1 (IC50 3.1 μg/mL) while it was non-cytotoxic. In contrast, orbiocrellin B (2) showed both antimalarial (IC50 2.1 μg/mL) and cytotoxic (NCI-H187 cells, IC50 0.70 μg/mL) activities.
