مولانامسعود عالم ندوی

مولانا مسعود عالم ندوی
ابھی حضرت الاستاذ رحمہ اﷲ کا غم نہ بھولا تھا کہ ندوہ کے ایک نامور فرزند مولانا مسعود عالم ندوی کا ماتم گسار ہونا پڑا، مرحوم نے چند گھنٹوں کی علالت کے بعد ۱۶؍ مارچ کو کراچی میں وفات پائی، وہ ندوہ کے اس دور کی بہترین پیداوار تھے۔ اﷲ تعالیٰ نے ان کو بڑی صلاحیتیں عطا فرمائی تھیں، عربی کے ممتاز ادیب و انشاء پر داز تھے انگریزی سے بقدر ضرورت واقفیت اور اردو کا ستھرا مذاق رکھتے تھے ان کے مضامین مصر و شام کے اخبارت و رسائل میں شائع ہوتے تھے، اور اہل زبان ادیبوں سے خراج تحسین حاصل کرتے تھے، ابتداء میں ندوہ میں ادب کے مدرس تھے، اسی زبان میں انھوں نے حضرت الاستاذؒ کی نگرانی میں عربی کا ایک رسالہ الضیاء نکالا تھا، جو چند سال نکلنے کے بعد بند ہوگیا، اس کے بعد اورنٹیل پبلک لائبریری پٹنہ میں فہرست نگار ہوگئے اور انگریزی میں عربی کے متفرق محظوطات کی فہرست کی ایک جلد مرتب کی جو چھپ کر شائع ہوگئی ہے۔
ان میں مسلمانوں کی دینی اصلاح کا جذبہ شروع سے تھا اور وہ وقتاً فوقتاً اصلاحی مضامین لکھتے رہتے تھے اس سلسلے میں شیخ محمد بن عبدولوہاب نجدی پر معارف میں ایک طویل مضمون لکھا تھا جو بعد میں ترمیم و اضافہ کے بعد کتابی صورت میں شائع ہوا، اسی جذبہ کے ماتحت وہ جماعت اسلامی میں شامل ہوگئے اور پاکستان ہجرت کر گئے تھے اس کے وہ بڑے سرگرم کارکن تھے، ان کی شرکت سے اس تحریک کو بڑا فائدہ پہنچا اس کو مضامین کے ذریعہ اسلامی ملکوں میں روشناس کرایا اس کی تبلیغ و اشاعت کے لیے عراق و شام کا سفر کیا اس کی متعدد اہم کتابوں کا عربی میں ترجمہ کیا ابھی حال میں ہندوستان میں اسلامی دعوت کی تاریخ اور...

قاعدہ استصحاب کی حجیت پر اہل سنت اور اہل تشیع کی آرا ء کا تحقیقی و تقابلی مطالعہ

This research article is a comparative study of arguments on Istishab from Ahli-eSunnah and Ahli-e-Tashyyo School of thoughts. Istishab means presumption of continuity. The word "Istishab" also means the continuance of companionship. Technically it means the presumption of constant of an earlier rule or it continued absence. In this sense it means the maintenance of status with respect to the rule. The previous rule is accepted. Unless a new rule is found that goes against. It is an easy reference one may refer to "Istishab-ul-hal" as the "accompanying rule". But the fact is that, Istishab-ul-hal is not a source for establishing new rules, but it is merely a set of presumptions. Istishab has vital importance in Islamic jurisprudence. But the authenticity and Significance of "Istishab" only can prove through arguments therefore decided to arrange a unique and comparative study of ‘Istihab” form Ahil sunnat and Ahil tashyy School of thoughts. So we can prove the rule of Istishab as an authentic and acceptable rule for all Muslim.

Phytochemical Studies of Lantana Camara Linn and Sturcture-Activity

The work embodied in the present thesis consists of two parts. Part A deals with the phytochemical studies on Lantana camara Linn., while part B describes the structure-activity relationship studies on some β-carboline alkaloids. A brief review of the biosynthesis of terpenoids with particular reference to the pentacyclic triterpenoids is also provided. PART A The introduction of Part A affords a review of the earlier contributions made in the chemistry and pharmacology of the genus Lantana and a brief account of the present work. Studies undertaken on the methanolic extract of the air dried aerial parts and roots of Lantana camara Linn. led to the isolation and structure elucidation of twenty four compounds including four new (17, 18, 21 and 23) and twenty known (1-16, 19, 20, 22 and 24) natural products. Compound 11 is hitherto unreported from aerial parts of the plant whereas compounds (4, 9 and 19) are reported for the first time from the genus Lantana. The constituents obtained in the present studies are listed below: Compounds obtained from aerial parts New Compounds 1. Lantanolide (17) 2. Lancamarolide (18) 3. Lancamarinic acid (21) 4. Lancamarinin (23) Known Compounds 5. Oleanonic acid (1) 6. b-Sitosterol (2) 7. Lantadene A (3) 8. 3-Oxo-11α-hydroxy-urs-12-ene-28-oic acid (4) 9. Oleanolic acid (5) 10. Ursolic acid (6) 11. Ursonic acid (7) 12. Betulinic acid (8) 13. 3β-Acetoxy Betulinic acid (9) 14. Lantadene B (10) 15. Pomonic acid (11) 16. Lantanilic acid (12) 17. Camaric acid (13) 18. Camarinic acid (14) 19. Lantaninilic acid (15) 20. Lantoic acid (16) 21. Stigmasterol (19) 22. Lantanolic acid (20) 23. Lantic acid (22) 24. β-Sitosterol-3-O-β-D-glucopyranoside (24) Compounds obtained from roots 1. Oleanonic acid (1) 2. Oleanolic acid (5) 3. Lantanilic acid (12) 4. β-Sitosterol-3-O-β-D-glucopyranoside (24) In the present investigation, the crude methanolic extract of the aerial parts of Lantana camara, its fractions and some pure compounds were evaluated for antileishmanial, nematicidal, mosquito larvicidal, anticancer and antioxidant activities. In addition, the extract and fractions were also evaluated for mosquito repellent, antibacterial, antifungal and insecticidal activities. Some pure compounds were also tested for immunomodulatory and enzyme inhibition activities. PART B The introduction of part B provides a review of the earlier contributions made in the chemistry and pharmacology of the β-carboline alkaloids – the harmine series of alkaloids. This part of the dissertation deals with the structure - activity relationship studies in the β-carboline alkaloids harmine (1), harmol (2) and harmalol (3) leading to the synthesis of thirty six derivatives (4-39) including eight new β-carbolines (20-25, 33 and 34) and five new tryptamine (35-39) derivatives along with several known compounds. Compounds 1 and 4-6 were tested for their leishmanicidal activity. Nematicidal activity of 2, 7, 8, 14-17 and 20-25 have also been determined. In addition compounds 2, 3 and 26-39 were tested for their antibacterial and antifungal activities. Some compounds were also investigated for their anticancer, chymotrypsin and urease inhibitory activities. The compounds synthesized in the present study are listed below: 1. 10-Bromo-11-methoxy-3-methyl-b-carboline (4) 2. 12-Bromo-11-methoxy-3-methyl-b-carboline (5) 3. 10,12-Dibromo-11-methoxy-3-methyl-b-carboline (6) 4. 10-Bromo-11-hydroxy-3-methyl-b-carboline (7) 5. 12-Bromo-11-hydroxy-3-methyl-b-carboline (8) 4 6. 11-Ethoxy-3-methyl-b-carboline (9) 7. 11-Butoxy-3-methyl-b-carboline (10) 8. 11-Isobutoxy-3-methyl-b-carboline (11) 9. 11-Pentoxy-3-methyl-b-carboline (12) 10. 11-Hexoxy-3-methyl-b-carboline (13) 11. 11-Heptoxy-3-methyl-b-carboline (14) 12. 11-Octoxy-3-methyl-b-carboline (15) 13. 11-Nonoxy-3-methyl-b-carboline (16) 14. 11-Decoxy-3-methyl-b-carboline (17) 15. 11-Allyloxy-3-methyl-b-carboline (18) 16. 11-Benzyloxy-3-methyl-b-carboline (19) 17. 11-2-Iodobenzyloxy-3-methyl-b-carboline (20) 18. 11-3-Iodobenzyloxy-3-methyl-b-carboline (21) 19. 11-4-Iodobenzyloxy-3-methyl-b-carboline (22) 20. 11-2-Nitrobenzyloxy-3-methyl-b-carboline (23) 21. 11-3-Nitrobenzyloxy-3-methyl-b-carboline (24) 22. 11-4-Nitrobenzyloxy-3-methyl-b-carboline (25) 23. 11-Acetoxy-3-methyl-b-carboline (26) 24. 11-Propionyloxy-3-methyl-b-carboline (27) 25. 11-Butyryloxy-3-methyl-b-carboline (28) 26. 11-Valeryloxy-3-methyl-b-carboline (29) 27. 11-Hexanoyloxy-3-methyl-b-carboline (30) 28. 11-Heptanoyloxy-3-methyl-b-carboline (31) 29. 11-Octanoyloxy-3-methyl-b-carboline (32) 5 30. 11-Nanoyloxy-3-methyl-b-carboline (33) 31. 11-Decanoyloxy-3-methyl-b-carboline (34) 32. 2-Acetyl-3-(2-nonanoylamidoethyl)-7-nonanoyloxyindole (35) 33. 2-Acetyl-3-(2-decanoylamidoethyl)-7-decanoyloxyindole (36) 34. 2-Acetyl-3-(2-trichloroacetamidoethyl)-7-trichloroacetoxyindole (37) 35. 2-Acetyl-3-[2-(2-trifloromethylbenzoyl)-amidoethyl]-7-(2- trifloromethyl benzoyloxy)-indole (38) 36. 2-Acetyl-3-[2-(3-trifloromethylbenzoyl)-amidoethyl)-7-(3- trifloromethyl benzoyloxy)-indole (39) Nematicidal activity was determined by Prof. Dr. Shaheena Fayyaz (Director) of the Institute of Nematological Research Center and Prof. Dr. Aly Khan (Director) of the Crop Disease Research Institute, Pakistan Agricultural Research Council, University of Karachi. Antimicrobial, antioxidant and immunomodulatory activities were tested by Prof. Dr. Aqeel Ahmed, Department of Microbiology, University of Karachi. Mosquito larvicidal and repellent activities were evaluated by Dr. M. Tariq Rajput, MAHQ Biological Research Centre, University of Karachi. Antileishmanial, anticancer, insecticidal and enzyme inhibition activities were determined by the bioassay screening section staff of this institute under the guidance of Prof. Dr. Muhammad Iqbal Choudhary. Extensive spectroscopic techniques such as UV, IR, EI-MS, HREI-MS, 1H- and 13C- NMR (Broad Band decoupled and DEPT), 2D NMR (1H-, 1H- COSY, NOESY, TOCSY, J-resolved, HMQC and HMBC) and chemical reactions were employed to elucidate the structures of the new compounds. The work embodied in the present dissertation has resulted in five research publications as listed in the list of publications.
