منشی عتیق احمد

منشی عتیق احمد
فروری ہی میں دارالمصنفین کے پریس کے منصرم منشی عتیق احمد صاحب نے لکھنؤ میں داعی اجل کو لبیک کہا، ان کے والد بزرگوار منشی صدیق احمد صاحب بھی جو مولانا مسعود علی ندوی مرحوم کے حقیقی بھانجے تھے، پریس کے انچارج رہ کر عرصہ تک دارالمصنفین کی خدمت کرتے رہے، منشی عتیق کو دمہ کا موذی مرض تھا جو بالآخر جان لیوا ثابت ہوا، دارالمصنفین میں وہ مولانا مسعود علی ندوی کے خاندان کی آخری یادگار تھے، اﷲ تعالیٰ مغفرت فرمائے اور پسماندگان کو صبر جمیل عطا کرے، آمین۔ (ضیاء الدین اصلاحی، مارچ ۱۹۹۸ء)

 

Analytical Study on Bill Discounting with Reference to Shār’Iah

With the growing economic industry, the importance of bill discounting is not obscured any more. It is undoubtedly one of the most important tools of trade financing. Now it has become very easy for importers and exporters to sale any product to a complete stranger anywhere in the world and get the bill against it discounted before its maturity date. That is why this tool is in the practice of all conventional banks. But regarding to shār’iah rulings its prevailed practice in conventional banks is not shār’iah compliance as this transaction consists of debt sale and interest. But due to it’s vitally need, Jurists of Islamic shār’iah have stepped forward with its different alternatives based on Můrabaha, Wākalāh, Můshāārkāh and Bāy’ Sālām in currency. In this article we have covered the causes behind the shār’iah rulings of prevailed bill discounting in conventional banks and addressed the Bāy’ Sālām as an alternative in currencies and its executive model in Islamic banks. Furthermore I have discussed the different opinions of modern scholars regarding these issues.

Synthesis of New Thiazolopyrimidine, Pyrazole, Stilbene-Triazine Derivatives and Tropane Auxiliary

This research work describes the synthesis and characterizationof some novel thiazolopyrimidine,pyrazole, stilbene-triazine derivatives and that of a tropane auxiliary. The in vitro and in silico studiesof synthesized compounds were also carried out. § Synthesis of thiazolopyrimidine derivatives (56-67) was carried out by one-pot multicomponent acid-catalyzed reaction of ethylacetoacetate and 2-aminothiazole and benzaldehyde substituted with electron-donating and electron-withdrawing groups with the aim to find some more potent antidiabetic and antibacterial drugs. An in vitro antidiabetic effect was evaluated in adult male BALB/c mice and antibacterial activities were tested against Gram positive and Gram negative bacteria. Some of the tested compounds proved to possess good to excellent activities compared to the reference drugs. An in silico molecular docking was also performed on synthesized compounds. The current study is expected to provide useful insights into the designof antidiabetic and antibacterial drugs and understanding the mechanism by which such drugs interact with RNA and diabetes target and exert their biochemical action. § A series of phenylhydrazono-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one derivatives (68-91)were conveniently synthesizedby the reaction of different anilines with ethylacetoacetate or acetylacetonefollowed by treatment with phenyl hydrazine. § Synthesis of pyrazole carboxamide derivatives (92-101) was carried out by multistep pathway starting from the reaction of substituted anilines and diethylmalonate. The resulting intermediate was then treated with benzaldehyde to afford ethyl 3-phenyl-2-(phenylcarbamoyl)acrylate which was converted to pyrazole derivatives by reacting with hydrazine hydrate.In vitro antidiabetic studies showed thatsome compounds possess better activities than the reference drugs and thederivative (94) having 2,4-dichloro substituents on phenyl ring was found to be most potent compound and was identified as the lead molecule for furtherstructural modifications. § A series of new optical brighteners (102-113)were efficiently synthesized by a facile three-step approach. 2,4,6-Trichloro-1,3,5-triazine was treated with different anilines and the resulting dichlorotriazinyl intermediates were further condensed with 4,4´-diaminostilbene-2,2´-disulfonic acid followed by nucleophilic substitution with ethanolamine to furnish new hybrid brighteners. UV/Visible absorptions were determined using freshly-prepared solutions in deionized water. The synthesized optical brighteners were also assessed for their efficacy as fluorescent brightening agents. § Synthesis of new thiourea-based bis-monochlorotriazine optical brighteners (114-125)was effected out by multistep synthetic pathway in good yields. § An efficient synthesis of some thioureas (126-145) was also accomplished.Substituted benzoyl chlorides were reacted with potassium thiocyanate to give the corresponding isothiocyantes intermediates, which on addition of separately-synthesized amino-2,4,6-triphenylpyridine, afforded thiourea derivatives in good yields. § In order to synthesize the enantio-pure α-alkylated aldehydes (which are widely recognized as important building blocks in asymmetric induction) from tropane-derived enamine, a highly efficient asymmetric multistep synthesis of a tropane auxiliary (153)was developed. § All the synthesized compounds were characterized on the basis of their physiochemical parameters and spectral data.
