گونہ تم سے ملی وفا مجھ کو

گو نہ تم سے ملی وفا مجھ کو
پھر بھی تم سے نہیں گلہ مجھ کو

میں بھی تم سے کنارا کر لیتا
کرنی آتی نہیں جفا مجھ کو

زندگانی گزارنے کے لیے
مرنا پڑتا ہے بار ہا مجھ کو

اُس کو مجبوریوں نے گھیرا تھا
کہہ نہ پایا وہ برملا مجھ کو

وہ نہ دھتکارتا مجھے تائبؔ
چاہے کرتا نہ کچھ عطا مجھ کو

Connecting Theory and Practice: Bridging Academic Feminism and Activism in Pakistan

Feminism is named as the demand for equality between men and women; however, it is not easily acceptable for the so-called super-gender called men, in any patriarchal society. It is not only a phenomenon but also a chapter of life that varies day by day, though is accepted by many communities, but difficult to adopt or accept in a patriarchal society as in Pakistan. There are many factors behind acceptance or rejection, which is debatable. Either the economy, politics, society, religion, or education is the aspect to enrol it in life. This article is the demonstration of factors, which is responsible for bridging the gap between academic feminism: which is being read to the generation, excluding the reality of the physique of gender, and the activism in feminism, which is being practised with social norms. This debate would be qualitative in nature. Though it concluded that Feminism in the society of Pakistan is not digestible for men members, however, the accelerator for equality or, even equity is slow but consistent and some of the changes are happening gradually.

Synthesis of Metal Based Derivatives of Sulfonamides and Their Biological Evaluation

The work presented in this thesis concerns the synthesis of various sulfonamide derived Schiff bases by the equimolar reaction of sulfonamides e.g., sulfamethazine, sulfadiazine, sulfathiazole, sulfanilamide, sulfamethaxazole, 4-(2-aminoethyl)benzene sulfonamide, 4- (methyl)benzenesulfonamide, sulfisoxazole and sulfaguanidine with the respective aldehydes such as 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde and 2- hydroxynaphthaldehyde. The free amino group (NH2) of the sulfonamide moiety condense with the carbonyl (HC=O) group of aldehydes to achieve the target of twenty- one new sulfonamide derived Schiff base (L1)–(L21) compounds. The structures of newly synthesized sulfonamides were elucidated by their physical, spectral (IR, 1H and 13 C NMR and mass) and analytical (CHN analysis) data. X-ray diffraction studies on nine sulfonamides were carried out to confirm the structures of 4-(5-chloro-2- hydroxybenzylideneamino)-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide (L1), 4- [(E)-(5-chloro-2-hydroxybenzylidene)amino]benzenesulfonamide (L4), 4-{2-[(5-chloro- 2-hydroxybenzylidene)amino]ethyl}benzenesulfonamide (L6), 4-chloro-2-[(E)-({4-[N- (3,4-dimethylisoxazol-5-yl)sulfamoyl]phenyl}iminio)methyl]phenolate (L8), 4-[(5- bromo-2-hydroxybenzylidene)amino]-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfon amide-4-bromo-2-[(E)-({4-[(4,6-dimethyl-pyrimidin-2-yl)sulfamoyl]phenyl}iminio) methyl]phenolate (L10), 4-[(E)-(5-bromo-2-hydroxyphenyl)methylideneamino]benzene sulfonamide (L13), 4-{[(E)-(5-bromo-2-hydroxyphenyl)methylidene]amino}-N-(5- methyl-1,2-oxazol-3-yl)benzenesulfonamide benzylidene)amino]ethyl}benzenesulfonamide (L14), 15 (L ) 4-{2-[(5-bromo-2-hydroxy and 4-bromo-2-((E)-{4-[(3,4- dimethylisoxazol-5-yl)sulfamoyl]phenyliminiomethyl)phenolate (L17). The synthesized sulfonamide derived Schiff base were used as ligands for complexation reaction with a number of metalloelements [Co(II), Ni(II), Cu(II) and Zn(II)] using in a molar ratio of L : M as 2 : 1. The nature of bonding and structure of all the metal(II) complexes have been deduced by their physical (conductivity, magnetic measurements), spectral (IR, 1H and 13 C NMR and electronic) and analytical (CHN analysis) data. The result of these studies revealed an octahedral geometry for all the metal(II) complexes. Due to amorphous nature of the metal(II) complexes, their crystals could not be formed for X-ray diffraction studies. In order to evaluate the biological role of these compounds and the effect of metalloelements on the nature of their biological activity, all the synthesized compounds were screened for their in vitro antibacterial, antifungal and cytotoxic activities against four Gram–negative (Escherichia coli, Shigella flexneri, Pseudomonas aeruginosa and Salmonella typhi) and two Gram–positive (Bacillus subtilis and Staphylococcus aureus) bacterial strains and against six fungal strains (Trichophyton longifusus, Candida albicans, Aspergillus flavus, Microsporum canis, Fusarium solani and Candida glabrata) using agar-well diffusion method. The result of these studies revealed that majority of the compounds showed significant (~80%) to moderate (~50%) antibacterial/antifungal activity. The activity however, was enhanced upon chelation/coordination with the metalloelements: some compounds, which were non- active, became active and moderate active became significantly active. Amongst all the compounds, the zinc(II) complexes showed the highest activity. The brine shrimp (Artemia salina) bioassay was also carried out to study in vitro cytotoxic activity. These studies revealed that several compounds displayed potent cytotoxic activity as LD50 in the range of 4.898 x 10-4 to 6.745 x 10-4 M/mL.
