درد ناآشنا کی یاد آئی
آج اُس دل رُبا کی یاد آئی
جانے کیوں بے وفا وہ یاد آیا
جانے کیوں بے وفا کی یاد آئی
یاد آئے وہ پیار کے موسم
اُس کی اک اک ادا کی یاد آئی
حشر کی تلخیوں کو جب سوچا
اُن کے لطف و عطا کی یاد آئی
بتکدوں میں گزار دی ہم نے
عمر بھر نہ خدا کی یاد آئی
جب مرض لا دوا ہوا تائبؔ
چارہ گر کو دوا کی یاد آئی
In this article, twelve scholars of District Haripur have been discussed for their significant contribution in Islamic sciences and various religious issues. The fact remains that District Haripur has remained the center for Islamic education wherein almost every school of thought has existed. In this article, those scholars are provided expression who despite been a part of some particular school of thought, have always encouraged intra-faith harmony. For example, "Al Ribat li Rad Hiyla al Isqat" by Maulana Mohammad Azam contains plenty of updated information on this issue. Similarly, another book called as "Mu'in-ul-'Aqaid” by Maulana Mohammad Hassan, provides grounds for rejecting the hypocrisy of society in a befitting manner. Before writing this article, a session was held with those scholars who are still alive whereas details of those dead were collected from their family members.
The stability of cyclic peptides and their self-assembling ability is an important aspect in the DNA recognition studies. Functionalization of cyclic peptides with nuclear bases may serve the purpose of mimicking and interacting with the DNA single strand. Stacking of the cyclic peptides after functionalzation may develop steric hinderance. L-Lysine, with side chain amino group, was selected to avoid these steric factors. Differently-protected L-lysine was transformed into its respective β-analogue using Arndt Eistert synthesis. These β-amino acids were utilized to synthesize cyclic β-tripeptide scaffolds through a multistep sequence. The scaffolds after deprotection were subjected to functionalization with the selected nuclear bases (adenine, thymine, cytosine and guanine) after conversion to their acetic acid derivatives. The nucleobase-functionalized cyclic β-tripeptide scaffolds were completely deprotected, purified by RP-HPLC and characterized by ESI and HRMS.
