This system release hormones that help control many important body functions. Dysfunctioning in the endocrine system may develop many disorders like diabetes, thyroid, growth disorders and sexual dysfunction. Poly cystic ovarian syndrome is one of the common endocrine disorder. PCOS is a common condition that causes a range of symptoms including irregular periods, unwanted hair growth, acne and weight problems. Increased circulating levels of testosterone can be considered as the major cause of development of polycystic ovarian syndrome. It is a male hormone, but women’s bodies make it too. Higher than normal testosterone level, makes women to experience PCOS. The physicians target on regular menstruation. In order to maintain the regular periods physicians basically administer Estrogen and Progesterone injection. Metformin is used during PCOS to treat insulin resistance developed in those women. Insulin resistance means that their bodies do not respond well to the hormone insulin that controls blood sugar levels. This causes blood sugar level to rise and this may lead to greater production of testosterone. Corticosteroids, vitamins, contraceptives pills are also prescribed for symptomatic treatment of PCOS. Changing of lifestyles may greatly help in management of poly cystic ovarian disorder. Regular exercise and weight management is the key for complete treatment of PCOS. This review contains all the information regarding PCOS.","PeriodicalId":19998,"journal":{"name":"Pharmaceutical and Biological Evaluations","volume":"58 1","pages":"14-26"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83190359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chagas’disease is caused by Trypanosoma cruzi and is a debilitating disease that has both acute and chronic forms. Many South Americans suffer from the chronic form of Chagas’disease, and there is no treatment currently available. Methods : In the chemical part, classical techniques of heterocyclic synthesis as well as usual methods of identification were used. In the biological part the cell proliferation test was used in vitro and the IC 50. Results : We synthesized a series of derivatives of 2-(1-methyl-5-nitro-2-imidazolyl)-5-substituted-1,3,4-thiadiazoles where 1-acetyl, 1-propyl and 1-nonyl were used as the substituent (4,6,7). Derivatives without nitro group were also synthesized (3,12) along with thiosemicarbazones (8,9,10) and a 5-(5-nitro-2-furanyl)-1,3,4-thiadiazol-2-amine (11). These compounds were evaluated using an in vitro test where were measured the cell proliferation. The derivatives that obtained the best results underwent further tests, in which their IC50 was calculated. The data revealed that two compounds (4,6) were effective against the parasite (IC50= 0.354 µM; IC50= 2.13 µM) and besides that, obtained the same results as the positive control, antimycim and rotenone. All proposed structures were obtained in satisfactory yields and purities. Conclusions : In conclusion, the in vitro trypanocidal activity makes these compounds promising leads in the development of an effective therapeutic agent. However, this study must be completed by additional tests with in vitro amastigote/macrophage models or in vivo mouse models. Analyzing the amide derivatives, compounds (4) and (6) were the ones that presented the best results.","PeriodicalId":19998,"journal":{"name":"Pharmaceutical and Biological Evaluations","volume":"96 1","pages":"40-51"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78956406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlimited use of antibiotics in humans and animals and in areas other than the treatment and prophylaxis of disease have resulted in a serious problem of drug resistance. Various attempts have been adopted to cope with the resistance problem and enhance the activity, or broaden the spectrum of drugs . Based on structure-activity relationship synthesis of new compounds has been one of the best approaches for better results. It has been demonstrated that Schiff base of some leading molecules and antibiotics possess good potential as more effective and safe drugs. Encouraged by reports on potential of Schiff’s bases as antimicrobial agents and to cope up with the current requirements of developing newer, safer and broad spectrum agents attempts were made to synthesize new Schiff’s bases. Methods : Our earlier in which structure activity relationship studies revealed that substitution by nitro and amino gp in Schiff’s base moiety resulted in the enhancement of activity. So further attempts were made to extend the series with incorporation of nitro and amino moiety by condensing o,m dinitro substituted acid hydrazide with various nitro/amino substituted benzaldehydes for increasing their antimicrobial potential. Results : Synthesized compounds were characterized on the basis of spectral studies (like UV, IR, and NMR). All the synthesized derivatives were screened further for their antibacterial effect.

Efavirenz and Lopinavir is an antiretroviral drug to treat HIV AIDS and inhibits cytochrome P450-3A4. Multiple CYP isoforms are involved in the metabolism of Glibenclamide like CYP2C8 and CYP3A4. Hence there is more possibility of Efavirenz and Lopinavir to inhibit the metabolism of Glibenclamide by inhibiting CYP 3A4. Methods : Efavirenz and Lopinavir (10 mg/kg,p.o.) alone and along with Glibenclamide (10 mg/kg, p.o.) was given to normal and diabetic rats. PK/PD parameters were studied. In the rats co-treated with Efavirenz and Lopinavir and Glibenclamide. Results : The pharmacokinetic parameters like clearance of Glibenclamide was reduced, peak plasma concentration, area under the plasma concentration time curve and elimination half-life were significantly increased when compared to pioglitazone treated rats. Conclusions : This study revealed that lopinavir and efavirenz affected the disposition of Glibenclamide in rats probably by the inhibition of CYP3A4, leading to increasing Glibenclamide concentrations that could increase the efficacy of Glibenclamide or it may causes severe hypoglycemia. Therefore, its warrants to use relatively less dose of Glibenclamide than the normal dose.","PeriodicalId":19998,"journal":{"name":"Pharmaceutical and Biological Evaluations","volume":"41 1","pages":"245-251"},"PeriodicalIF":0.0,"publicationDate":"2017-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91387932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
