Evaluation of the antiplasmodial and anti-Toxoplasma activities of several Indonesian medicinal plant extracts.

Ethnopharmacological Relevance: Malaria, caused by Plasmodium parasites, remains a significant global health challenge, particularly in tropical and subtropical regions. At the same time, the prevalence of toxoplasmosis has been reported to be 30% worldwide. Traditional medicines have long played a vital role in discovering and developing novel drugs, and this approach is essential in the face of increasing resistance to current antimalarial and anti-Toxoplasma drugs.

Towards halal pharmaceutical: Exploring alternatives to animal-based ingredients.

Halal is a crucial concept for Muslim consumers regarding consumed products, including pharmaceutical ingredients, which are essential in modern medicine. To address the issue of using porcine-sourced ingredients in pharmaceuticals, it is essential to search for halal alternatives derived from poultry, animal by-products from meat processing, marine sources, and plants. However, the complexity of this problem is further compounded by the rapid advances in innovation and technology, which can lead to adulteration of ingredients derived from pigs.

Nanoparticle-Based Antioxidants in Stress Signaling and Programmed Cell Death in Breast Cancer Treatment.

Breast cancer (BC) is a complex and heterogeneous disease, and oxidative stress is a hallmark of BC. Oxidative stress is characterized by an imbalance between the production of reactive oxygen species (ROS) and antioxidant defense mechanisms. ROS has been implicated in BC development and progression by inducing DNA damage, inflammation, and angiogenesis.

Structure elucidation of a new bicoumarin derivative from the leaves of Dysoxylum parasiticum (Osbeck) Kosterm.

A new bicoumarin derivative, bidysoxyletine (1), was isolated from the leaves of Dysoxylum parasiticum (Osbeck) Kosterm. The structure of 1 was elucidated by analysis of NMR, UV, IR, HR-ESITOFMS, and DDFT approach using the B3LYP exchange-correlation function for C NMR and UV spectroscopic data. The results indicated that the structure of 1 possessed a dibenzonapthyrone skeleton.

Inhibition of bacillus spores germination by cinnamon bark, fingerroot, and moringa leaves extract.

This study was intended to discover the natural food preservatives by comparing the antibacterial effect of the ethanolic extract of cinnamon bark, finger root, and moringa leaves toward both the vegetative cells and spores. The antibacterial activities of the investigated extracts were assessed against cells using the agar diffusion method. Whereas the sporicidal test was performed by observing the colony growth, after various times of incubation (1, 3, and 5 h).

Bidysoxyphenols A-C, dimeric sesquiterpene phenols from the leaves of Dysoxylum parasiticum (Osbeck) Kosterm.

Three new sesquiterpene phenol dimers, bidysoxyphenols A-C (2-4), along with two known compounds, namely sesquiterpene phenol (1) and ionone derivatives (5), were isolated from the leaves of Dysoxylum parasiticum (Osbeck) Kosterm. The structures of these new compounds, including their absolute configurations, were elucidated by nuclear magnetic resonance spectroscopy, ultraviolet spectroscopy, infrared spectroscopy, high-resolution electrospray ionization time-of-flight mass spectrometry, and electronic circular dichroism. Compounds 1 and 2 showed cytotoxicity against human promyelocytic leukemia cells, with IC values of 18.

Antioxidant p-terphenyl compound, isolated from edible mushroom, Boletopsis leucomelas.

A new acetyl p-terphenyl derivative, boletopsin 15, was isolated from the ethyl acetate extract of fruit bodies of the Basidiomycete Boletopsis leucomelas, together with 4 known compounds. The structures of these compounds were elucidated by spectral analysis as well as by directly comparing the spectral data of the new compound with those of known compounds. The free radical-scavenging activity of the compounds was assayed using the 2,2-diphenyl-1-picrylhydrazyl scavenging method.

The 2,3-epoxy naphthoquinol produced by endophyte M-211.

A novel 2,3-epoxy naphthoquinol, named (6,7,8)-theissenone A (), possessing an oxatricyclo[5.4.0.

Two new octahydronaphthalene derivatives, trichodermic acids C and D produced by sp. HN-1.1.

Two new octahydronaphthalene derivatives, trichodermic acid C () and trichodermic acid D (), along with known analogs, trichodermic acid (), trichodermic acid A () and trichodermic acid B (), were isolated from an ethyl acetate extract of endophytic strain sp. HN-1.1.

Cochlioquinone derivatives produced by coculture of endophytes, Clonostachys rosea and Nectria pseudotrichia.

Three new meroterpenoid derivatives, furanocochlioquinol (1) and furanocochlioquinone (2), as well as nectrianolin D (3), together with two known biogenetically related compounds 4 and 5 were isolated from a mixed culture of two mangrove-derived fungi, Clonostachys rosea B5-2 and Nectria pseudotrichia B69-1. The structures of 1-3 were deduced based on the interpretation of HRMS and NMR data. Compounds 1-5 exhibited cytotoxicity against human promyelocytic leukemia (HL60) cells with IC values ranging from 0.
