Orchid Chemicals & Pharmaceuticals, or Orchid Pharma since its recent name change in 2015, was established in 1992 in Chennai to manufacture antibiotics, and entered drug discovery in 2001 with projects in the areas of anti-infectives and treatments for pain.32197 In 2002, the company engaged in a joint venture to develop US-based firm Bexel Biotechnology’s BLX-1002, an oral, non-PPAR AMPK activator for the treatment of diabetes,198 later repositioned for NASH (2012), but no further progress has been reported recently.197 In 2008, Orchid invested in Diakron Pharmaceuticals, a US-based company that had an exclusive license to MSD′s investigational oral anticoagulant drug, a direct thrombin inhibitor later known as DPOC-4088 (or DP-4088),199 which reached Phase 1 clinical studies in Europe in 2012 (Supporting Information Table 6b, entries 5–6).200 The company’s own internal discovery efforts had a broad therapeutic focus, covering infectious diseases, inflammation, pain, oncology, metabolic disorders, and CNS diseases. OCID-2987,197201 a PDE4 inhibitor for the treatment of inflammatory disorders such as COPD, completed successfully Phase 1 studies in Europe in 2012, and OCID-4681 29,202203 a histone deacetylase (HDAC) inhibitor for cancer had received approval in 2011 for Phase 1 studies for solid tumors in India, but we assume both have been abandoned, as cancer and inflammation are not mentioned in the company’s latest annual reports.197 Two additional compounds were abandoned at the preclinical stage: OCID-5005, a STAT-3/IL-6 inhibitor for oncology, and a unnamed Th1/Th2 cytokine synthesis inhibitor for inflammation (Supporting Information Table 2a, entries 134–138).197 Financial issues led Orchid, as of 2009, to sell parts of its business to Hospira (now part of Pfizer). As a consequence, no progress has been reported on its discovery programs since 2010, and no further NCE patent application has been published since 2012. However, in 2013 Orchid licensed its broad-spectrum β-lactamase inhibitor OCID-5090, a zwitterionic N-methylated tazobactam derivative, to the German Allecra Therapeutics for a 20 % stake in the company, for use in combination with antibiotics to treat multidrug-resistant gram negative bacteria.204207 Allecra’s lead compound AAI202, a combination of cefepime and AAI101/OCID-5090 30, is currently in Phase 1 studies in France.208209
