The Complaint alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company's business, operations, and prospects. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) Scynexis's lead product, SCY-078, entailed substantial undisclosed health and safety risks; (ii) consequently, the Company had overstated the drug's approval prospectus and/or commercial viability; and (iii) as a result of the foregoing, Scynexis's public statements were materially false and misleading at all relevant times. On March 2, 2017, post-market, Scynexis issued a press release, attached as Exhibit 99.1 on Form 8-K, entitled, "Scynexis delays initiation of new clinical studies using the IV formulation of SCY-078 at FDA's request," announcing the FDA's clinical hold on clinical trials for the intravenous formulation of the Company's lead product candidate, SCY-078. The Company stated that "[t]he clinical hold decision was issued by the FDA following a review of three mild-to-moderate thrombotic events in healthy volunteers receiving the IV formulation of SCY-078 at the highest doses and highest concentrations in a Phase 1 study." On this news, Scynexis's share price fell $0.57, or 17.43%, to close at $2.70 on March 3, 2017. The Pomerantz Firm, with offices in New York, Chicago, Florida, and Los Angeles, is acknowledged as one of the premier firms in the areas of corporate, securities, and antitrust class litigation. Founded by the late Abraham L. Pomerantz, known as the dean of the class action bar, the Pomerantz Firm pioneered the field of securities class actions. Today, more than 80 years later, the Pomerantz Firm continues in the tradition he established, fighting for the rights of the victims of securities fraud, breaches of fiduciary duty, and corporate misconduct. The Firm has recovered numerous multimillion-dollar damages awards on behalf of class members. See www.pomerantzlaw.com.

Background Since its isolation in 1970, and discovery of its potent inhibitory activity on T-cell proliferation, cyclosporin A (CsA) has been shown to play a significant role in diverse fields of biology. Furthermore, chemical modification of CsA has led to analogs with distinct biological activities associated with its protein receptor family, cyclophilins. Scope of review This review systematically collates the synthetic chemistry performed at each of the eleven amino acids, and provides examples of the utility of such transformations. The various modifications of CsA are traced from early, modest chemistry performed at the unique Bmt residue, through the remarkable use of a polyanion enolate that can be stereoselectively manipulated, and onto application of more recently developed olefin metathesis chemistry to prepare new CsA derivatives with unexpected biological activity. Major conclusions The myriad biological activities of CsA and its synthetic derivatives have inspired the development of new approaches to modify the CsA ring. In turn, these new CsA derivatives have served as tools in the discovery of new roles for cyclophilins. General significance This review provides information on the types of cyclosporin derivatives that are available to the many biologists working in this field, and should be of value to the medicinal chemist trying to discover drugs based on CsA.

Cyclophilins (Cyps) are ubiquitous proteins that effect the cis-trans isomerization of Pro amide bonds, and are thus crucial to protein folding. CypA is the most prevalent of the ∼19 human Cyps, and plays a crucial role in viral infectivity, most notably for HIV-1 and HCV. Cyclophilins have been shown to play key roles in effective replication of a number of viruses from different families. A drug template for CypA inhibition is cyclosporine A (CsA), a cyclic undecapeptide that simultaneously binds to both CypA and the Ca 2+-dependent phosphatase calcineurin (CN), and can attenuate immune responses. Synthetic modifications of the CsA scaffold allows for selective binding to CypA and CN separately, thus providing access to novel, non-immunosuppressive antiviral agents. © 2013 Elsevier Ltd.

Amitraz, a formamidine acaricide, has been reported to act as a synergist of contact insecticides and acaricides in both agriculture and animal health. A laboratory contact test was therefore conducted to determine whether amitraz at 12. 5 ppm could improve the contact potency of fipronil on ticks. A controlled glass vial bioassay was used to assess the efficacy of fipronil alone, amitraz alone, and fipronil plus amitraz on unfed adult Rhipicephalus sanguineus. Assessments of lethality were made at 6, 24, and 48 h after the introduction of the ticks to the vials. No significant mortality was observed in the control treatment or in the amitraz alone treatment. Concentration and time dependent mortality rates were observed in ticks exposed to fipronil alone or fipronil plus amitraz, with higher mortality observed in the latter group. Results from this study gave synergistic EC50 ratios between fipronil alone and fipronil plus amitraz of >7.3, 137 and 97 at 6, 24, and 48 h, respectively. A similar response was seen at the EC90 level. These results indicate that fipronil was synergized by amitraz in this adult tick residual contact study. The addition of amitraz to fipronil also provided a significant improvement in the speed of kill. © 2011 Springer Science+Business Media B.V.

Historically, one of the key problems in neglected disease drug discovery has been identifying new and interesting chemotypes. Phenotypic screening of the malaria parasite, Plasmodium falciparum has yielded almost 30,000 submicromolar hits in recent years. To make this collection more accessible, a collection of 400 chemotypes has been assembled, termed the Malaria Box. Half of these compounds were selected based on their drug-like properties and the others as molecular probes. These can now be requested as a pharmacological test set by malaria biologists, but importantly by groups working on related parasites, as part of a program to make both data and compounds readily available. In this paper, the analysis and selection methodology and characteristics of the compounds are described. © 2013 Spangenberg et al.

PURPOSE OF REVIEW: Boron-based drugs represent a new class of molecules that have been found to exhibit attractive properties and activities against a number of protozoans causative of neglected tropical diseases. RECENT FINDINGS: This review highlights recent advances in discovery of potential treatments for human African trypanosomiasis, malaria and Chagas disease from a class of boron-containing drugs, the benzoxaboroles. SUMMARY: Research at several biotechnology companies, sponsored by product development partners (PDPs), has been successful in identifying a novel class of boron-based drugs, the benzoxaboroles, as potential treatments for neglected tropical diseases. This work was based, in part, on the earlier observation of antifungal, antibacterial and anti-inflammatory activities of the benzoxaboroles. The unique properties of boron, namely its ability to reversibly interact with biochemical targets through an empty p-orbital, are important to the success of these new drug candidates. Physicochemical and pharmacokinetic properties of the boron-based compounds are consistent with features required for oral absorption, metabolic stability and low toxicity - all important for progression of this class to clinical trials. © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins.
