Accuracy Of Prediction

In the present study, the application of a wide variety of topological descriptors was investigated for predicting hydrophobicity (clogP) of isatin analogues. A total of four topochemical indices selected through decision tree (DT) were used for the development of single index based models using moving average analysis (MAA). The overall accuracy of prediction varied from a minimum of 95% to a maximum of 98% with regard to hydrophobicity.The values of sensitivity, specificity and Mathew's correlation coefficient for all MAA based models with regard to hydrophobicity (clogP) was found to be =78%, =94% and =0.85 respectively, suggesting robustness of proposed models. Since the compounds with high clogP values were found effective in carboxylesterases (CEs) inhibition, therefore, highly hydrophobic ranges of proposed MAA models can easily be exploited for the design and development of potent CEs inhibitors.

Kuwanon-H merupakan senyawa flavonoid dari kulit akar  murbei (Morus alba L) yang secara in vitro berpotensi sebagai anti-HIV dibanding senyawa flavonoid lainnya yang terkandung dalam kulit akar murbei seperti morusin dan morusin 4′-glucosida. Telah dilakukan penelitian desain senyawa, penambatan molekular menggunakan ArgusLab 4.0.1 dengan metode ArgusDock, penerapan aturan Lipinski’s Rule of Five menggunakan Marvin Sketch 5.2.5.1dan uji toksisitas menggunakan aplikasi Toxtree secara in silico terhadap turunan senyawa kuwanon-H. Desain enam puluh senyawa turunan kuwanon-H dilakukan dengan cara model pendekatan Topliss pada rantai samping alifatiknya. Hasil penambatan ke-60 turunan senyawa pada reseptor HIV-1 Reverse Transcriptase (1REV) menunjukkan bahwa senyawa terbaik yaitu 3-[(2Z)-3-(siklopropilmetil)but-2-en-1-il]-8-[6-({3-[(2Z)-3-(siklopropilmetil)but-2-en-1-il]-2,4-dihidroksifenil}karbonil)-5-(2,4-di-hidroksilfenil)-3-metilsiklohek-2-en-1-il]-2-(2,4-dihidroksilfenil),7-dihidroksi-4H-kromen-4-on dengan nilai energi bebas yang lebih rendah (-12.5798 kkal/mol) dibandingkan ligan asli (-11.0445 kkal/mol) dan kuwanon-H (-11.0189 kkal/mol). Senyawa terbaik ini tidak memenuhi aturan Lipinski’s Rule of Five. Hasil prediksi uji toksisitas senyawa terbaik menurut parameter Cramer Rules termasuk kategori III, yaitu diprediksi memiliki toksisitas tinggi, menurut parameter Benigni/Bossa Rulebase diprediksi senyawa yang diuji tidak bersifat karsinogenik, genotoksik, dan nongenotoksik, sedangkan menurut parameter Kroes TTC decision tree diprediksi senyawa uji berpotensi toksik.DOI:http://dx.doi.org/10.15408/jkv.v4i1.6867

SummaryLevels of anticardiolipin antibodies (ACA) were measured in 55 patients with haemophilia A in serum samples obtained in 1983 and in 1987. Twenty-one patients were negative for anti HIV-1 antibodies in 1983 and remained negative in 1987; 34 patients had anti HIV-1 antibodies in 1983; 17 of these latter patients remained asymptomatic, whereas 17 patients developed ARC or AIDS during the 4 years follow-up. Thirteen anti HIV-1 negative patients had elevated ACA levels in 1983; subsequently, a significant decrease was observed in all these subjects (p <0.001). All anti HIV-1 positive patients had elevated ACA levels in 1983; normal values were found in 9 patients in 1987. Yet, these changes were not significant (p >0.05). ACA levels were significantly higher in HIV-1 infected patients than in those without anti HIV-1 antibodies (p <0.05). There was no difference of ACA levels between the two anti HIV-1 positive patient groups, be it in 1983 or be it in 1987 (p >0.05). There was no correlation of ACA levels with serum IgG concentrations, CD4+ lymphocytes, or the consumption of factor VIII concentrates.
