TL;DR: The involvement of inflammation in ALS is confirmed and the need to develop surrogate markers to check the progression of this disease is confirmed.
Abstract: The role of cytokines in the pathophysiology of amyotrophic lateral sclerosis (ALS) and its relation to clinical outcome has not been clearly defined. We evaluated tumor necrosis factor-alpha (TNF-α), interferon-γ (IFN-γ) and nitric oxide (NO) levels in the serum of 22 ALS patients and 20 controls. Serum TNF-α levels and IFN-γ levels were significantly (P < 0.001) elevated in ALS patients. We also observed NO levels to be significantly (P < 0.05) increased with respect to normal subjects. We further noticed positive correlation between the duration of ALS and these proinflammatory molecule levels. Exitotoxicity and oxidative stress are known to play a crucial role in the neurodegeneration observed in ALS. Since high levels of TNF-α are known to be cytotoxic, it could be that a complex interplay of these effectors may be one of the factors underlying the progression of ALS. This study confirms the involvement of inflammation in ALS and the need to develop surrogate markers to check the progression of this disease.

TL;DR: Licochalcone A (I), isolated from the roots of Chinese licorice, is the most promising antimalarial compound reported so far and two similar chalcones, medicagenin (II) and munchiwarin (III), from Crotalaria medicagenia, which exhibitedAntimalarial activity against Plasmodium falciparum .
Abstract: Licochalcone A (I), isolated from the roots of Chinese licorice, is the most promising antimalarial compound reported so far. In continuation of our drug discovery program, we isolated two similar chalcones, medicagenin (II) and munchiwarin (III), from Crotalaria medicagenia, which exhibited antimalarial activity against Plasmodium falciparum. A library of 88 chalcones were synthesized and evaluated for their in vitro antimalarial activity. Among these, 67, 68, 74, 77, and 78 exhibited good in vitro antimalarial activity against P. falciparum strains 3D7 and K1 with low cytotoxicity. These chalcones also showed reduction in parasitemia and increased survival time of Swiss mice infected with Plasmodium yoelii (strain N-67). Pharmacokinetic studies indicated that low oral bioavailability due to poor ADME properties. Molecular docking studies revealed the binding orientation of these inhibitors in active sites of falcipain-2 (FP-2) enzyme. Compounds 67, 68, and 78 showed modest inhibitory activity against th...

TL;DR: A rapid and sensitive analytical method was developed using reverse phase high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry for qualitative analysis to determine the array of bioactive phytochemicals and their variations in different plant parts.
Abstract: Terminalia arjuna is a medicinal plant used in ethnomedicine and the codified traditional medicine. A number of active constituents are reported, but there is no information on the whole range of gallic and ellagic acid derivatives present in this plant A rapid and sensitive analytical method was developed using reverse phase high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (HPLC-ESI-QTOF-MS/MS) for qualitative analysis to determine the array of bioactive phytochemicals and their variations in different plant parts viz. bark, unripe fruit, ripe fruit, leaf, root and stem. Separation was performed on a Thermo Betasil C8 column (250 mm x 4.5 mm, 5 µm) with a mobile phase consisted of 0.1% formic acid aqueous solution and acetonitrile at a flow rate of 0.5 mL/min in 55 min. A wide range of constituents of T. arjuna were characterized and broadly grouped as 27 gallic acid and 52 ellagic acid derivatives.
