Multidrug resistance reversal activity of extract and a rare dimeric naphthoquinone from Diospyros lotus

A dimeric naphthoquinone namely dihydrodyspyrole R [1] was purified once more from Diospyros lotus. Dihydrodyspyrole R and chloroform fractions were evaluated for their effects on the reversion of multidrug resistance [MDR]. The compounds [1] and extract exhibited promising MDR reversing effect in a dose-dependent manner against mouse T-lymphoma cell line. Molecular docking of compound 1 revealed the correlation between in-silico with in-vitro results. The molecular docking results showed that compound 1 is bind closely where co-crystal ligand of P-gp is present. But usually, computational investigation predicts that, if a compound gives lesser score then compound will exhibit good activity. Hence, the docking scores of compound 1 are the near to the Rhodamine. It is conclude that there are certain important structural features of compound 1which are responsible for the inhibiting potency of P-gp from mice. The computational Petra/Osiris/Molinspiration [POM] analysis confirms the possibility of use of compound 1 without side effect or less toxicity risks

In vitro antimalarial and xanthine oxidase inhibition of 2-Aminoanthraquinone

In the present research study 2-Aminoanthraquinone were scrutinized for their antimalarial and Xanthine oxidase inhibitor potential. It demonstrated marked concentration dependent antimalarial activity with maximum effect of 89.06% and with IC[50] of 34.17 micro M. Regarding Xanthine oxidase inhibitor activity, it evoked significant effect with 57.45% activity with IC[50] value of 81.57.19 micro M. In conclusion, 2-Aminoanthraquinone showed potent antimalarial and xanthine oxidase inhibitory activity

Prevalence of pneumoconiosis among coal miners of Cherat, district Nowshera - Pakistan

The objective of this study was to assess the prevalence of pneumoconiosis among coal miners. This cross-sectional study was conducted among 400 coalminers of Cherat, District Nowshera, KPK, Pakistan, from July 2012 to June2013. Coal miners who worked for more than six months were included. Medical camps were arranged in study areas in which Pulmonary Function Tests and CXR was conducted to estimate the prevalence of pneumoconiosis. The demographic variables were also noted on a semi structured proforma. The medical examinations of coal miner's revealed that approximately71% [n=284] of coal miners have sign and symptoms of occupational respiratory health problems. The coal miners showed an increased prevalence of coal workers pneumoconiosis [49.50%] i.e. about 47% [n=188] on Chest X-rays [P/A View] and 52.50% [n=210] on Pulmonary Function Tests has findings of coal workers pneumoconiosis. Only 31.75% [n=127] of coal miners have normal pulmonary function tests and 35% [n=140] have normal chest x-ray findings during medical assessment. The prevalence of the pneumoconiosis was high [49.50%] among the Cherat coal miners; and needs proper consideration and attention from the health sector and mining department in order to reduce the high burden of pneumoconiosis among coal miners
