RESUMEN
PURPOSE OF REVIEW: In this review article, we discuss myofascial-related chronic pelvic pain, pathophysiology, symptomology, and management options. RECENT FINDINGS: Despite high prevalence of myofascial pelvic pain, screening is not routinely performed by providers. Treatment modalities include pelvic floor physical therapy, pelvic floor trigger point injections with anesthetics or botulinum toxin A and cryotherapy. Other adjunct modalities, such as muscle relaxants and intravaginal benzodiazepines, are used, but data regarding their effectiveness is sparse. SUMMARY: Myofascial pelvic pain is an important, though overlooked component of chronic pelvic pain. Multimodal, multidisciplinary approach including patient education, pelvic floor physical therapy, and trigger point injections is the mainstay of the management of myofascial pelvic pain.

A simple and efficient one-pot three-component synthetic route to highly substituted and functionalizable piperazines in high yields with excellent stereoselectivity (de, ee >99%) is reported. The SN2-type ring-opening of N-activated aziridines by anilines followed by Pd-catalyzed annulation with propargyl carbonates gives rise to the final piperazine products.
RESUMEN
Dengue, caused by dengue virus (DENV), is now endemic in nearly 100 countries and infection incidence is reported in another 30 countries. Yearly an estimated 400 million cases and 2200 deaths are reported. Effective vaccines against DENV are limited and there has been significant focus on the development of effective antiviral against the disease. The World Health Organization has initiated research programs to prioritize the development and optimization of antiviral agents against several viruses including Flaviviridae. A significant effort has been taken by the researchers to develop effective antivirals against DENV. Several potential small-molecule inhibitors like efavirenz, tipranavir and dasabuvir have been tested against envelope and non-structural proteins of DENV, and are in clinical trials around the world. We recently developed one small molecule, namely 7D, targeting the host PF4-CXCR3 axis. 7D inhibited all 4 serotypes of DENV in vitro and specifically DENV2 infection in two different mice models. Although the development of dengue vaccines remains a high priority, antibody cross reactivity among the serotypes and resulting antibody-dependent enhancement (ADE) of infection are major concerns that have limited the development of effective vaccine against DENV. Therefore, there has been a significant emphasis on the development of antiviral drugs against dengue. This review article describes the rescue effects of some of the small molecule inhibitors to viral/host factors associated with DENV pathogenesis.

A novel synthetic approach for the construction of 1,2,3,3a,4,5-hexahydroimidazo[1,2-a]quinolines in good yields (up to 75%) with excellent stereoselectivity (dr up to 94:6, ee up to >99%) under one-pot domino ring-opening cyclization (DROC) conditions has been developed. The DROC protocol proceeds through a Lewis acid catalyzed SN2-type ring-opening of activated aziridines with N-propargylanilines followed by intramolecular cyclization comprising concomitant hydroarylation and hydroamination steps in a domino fashion.
RESUMEN
Two efficient, modular, step- and pot-economic strategies to access various 5,6,7,12-tetrahydrobenzo[2,3]azepino[4,5-b]indoles and 6,7-dihydro-5H-benzo[5,6][1,4]diazepino[1,7-a]indoles are disclosed that advance via SN2-type regioselective ring opening of enantiopure aziridines with 2-(2-bromophenyl)-1H-indoles at their C3 and indolyl N centers, respectively, followed by Cu-mediated C-N cyclization which furnishes the products in excellent yields with outstanding enantiomeric excesses (up to >99%).
