     FIELD 
     Provided are uses of selective aquaporin inhibitors, e.g., of aquaporin-4 or aquaporin-2, e.g., certain phenylbenzamide compounds, for the treatment or prophylaxis of transplant rejection. 
     BACKGROUND 
     Aquaporins are cell membrane proteins that act as molecular water channels to mediate the flow of water in and out of the cells. While there is some degree of passive diffusion or osmosis of water across cell membranes, the rapid and selective transport of water in and out of cells involves aquaporins. These water channels selectively conduct water molecules in and out of the cell, while blocking the passage of ions and other solutes, thereby preserving the membrane potential of the cell. Aquaporins are found in virtually all life forms, from bacteria to plants to animals. In humans, they are found in cells throughout the body. 
     Transplantation is the transfer (engraftment) of cells, tissues, or organs from a donor to a recipient. Transplant recipients face a lifetime of immunosuppressive therapy and the risk of losing the new organ due to rejection. In addition, immunosuppressants suppress all immune responses and contribute to post-transplantation complications, including death due to overwhelming infection. Although improvements have been made in the transplantation process, rejection remains a common complication following transplantation. Transplant rejection occurs when the immune system of the transplant recipient attacks the transplanted organ or tissue. 
     Organ preservation, for example during storage and transport, is a major determinant of graft outcome after revascularization. Organ transplants have a higher frequency of success when performed immediately after excision from the donor. 
     There remains a need for methods to promote cell, tissue, and organ transplantation tolerance in patients. In addition, there remains a need for methods of tissue and organ preservation.

     DETAILED DESCRIPTION 
     The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. 
     Aquaporin-4 (AQP4) is reportedly found in mammalian hearts at both the mRNA and protein level. Aquaporin-2 (AQP2) is the primary route of water movement at the collecting duct in the kidney. Several AQPs are reportedly expressed in the lung and airways: AQP1 in microvascular endothelia, AQP3 and AQP4 in airway epithelia, and AQP5 in type I alveolar epithelial cells, submucosal gland acini, and a subset of airway epithelial cells. AQP0, AQP1, AQP4, AQP8, and AQP9 are reportedly expressed in liver cells at both the mRNA and protein level. 
     Certain aquaporin inhibitors are described in International Application No. PCT/US2013/040194, which is incorporated herein by reference in entirety. 
     Damage to organs during transplantation occurs in two phases. 
     The first, the warm ischemic phase, includes the time from the interruption of circulation to the donor organ to the time the organ is flushed with hypothermic preservation solution. The second, the cold ischemic phase, occurs when the organ is preserved in a hypothermic state prior to transplantation into the recipient. 
     The stability of the cell membrane to chemical and water permeability depends on the integrity of the lipid bilayer and on control of temperature, pH, and osmolarity. Organ ischemia and preservation may disrupt these relations. Lowering the temperature may cause changes in membrane stability and may alter the function of membrane-bound enzymes. Hypothermia-induced structural changes in the membrane may increase permeability, which contributes to cell swelling. Hypertonic organ-preservation solutions may minimize those alterations. 
     The sodium-potassium adenosine triphosphatase (Na—K ATPase) maintains the ionic composition of the cell. The pump may be disrupted because of the lack of adenosine triphosphate (ATP) production and by excessive production of hydrogen ions because of anaerobic metabolism during ischemia. When the sodium-potassium ATPase pump is paralyzed, potassium moves out of the cell and diffuses down its concentration gradient to the extracellular space, whereas sodium, which is normally kept at a low concentration in the cell, enters. This ionic shift may cause cell swelling and disruption of the cell if unchecked. Preservation solutions with electrolyte compositions similar to the milieu inside the cell may minimize the osmotic gradients. 
     Transplants may be the patient&#39;s own tissue (autografts, e.g., bone, bone marrow, and skin grafts), genetically identical (syngeneic [between monozygotic twins]) donor tissue (isografts), genetically dissimilar donor tissue (allografts or homografts), or grafts from different species (xenografts or heterografts). Transplanted tissue may be cells (as for hematopoietic stem cell [HSC], lymphocyte, and pancreatic islet cell transplants), parts or segments of an organ (as for hepatic or pulmonary lobar transplants and skin grafts), or entire organs (as for heart or kidney transplants). 
     Allograft transplant recipients are at risk of graft rejection; the recipient&#39;s immune system recognizes the graft as foreign and seeks to destroy it. Rejection may be hyperacute, accelerated, acute, and/or chronic. 
     Hyperacute rejection includes rejection that occurs within 48 hours of transplantation and may be caused by preexisting complement-fixing antibodies to graft antigens (presensitization), for example in the case of xenografts. Hyperacute rejection may be characterized by small-vessel thrombosis and graft infarction. 
     Accelerated rejection includes rejection that occurs 3 to 5 days after transplantation and is caused by preexisting noncomplement-fixing antibodies to graft antigens. Accelerated rejection may be characterized histopathologically by cellular infiltrate with or without vascular changes. 
     Acute rejection includes graft destruction after transplantation, which may be caused by a T cell-mediated delayed hypersensitivity reaction to allograft histocompatibility antigens. Acute rejection may be mediated by a de novo anti-graft T-cell response, not by preexisting antibodies. Acute rejection may occur about 5 days after transplantation. Acute rejection may be characterized by mononuclear cellular infiltration, with varying degrees of hemorrhage, edema, and necrosis. Vascular integrity may be maintained, although vascular endothelium may be a primary target. 
     Chronic rejection includes graft dysfunction, often without fever, typically occurring months to years after transplantation but sometimes within weeks. There may be multiple causes, including early antibody-mediated rejection, periprocedural ischemia and reperfusion injury, drug toxicity, infection, and vascular factors (e.g., hypertension, hyperlipidemia). Proliferation of neointima consisting of smooth muscle cells and extracellular matrix (transplantation atherosclerosis) may gradually and eventually occlude vessel lumina, resulting in patchy ischemia and fibrosis of the graft. 
     Without intending to be bound by theory, it is hypothesized that if damage to the transplanted organ can be minimized at the time of transplant, this reduces the risk of subsequent rejection, including acute and/or chronic rejection. Thus, prophylaxis of acute or chronic rejection would include actions taken around the time of the transplant, as well as administration of immunosuppressive and/or anti-inflammatory agents administered later for specific control of lymphocyte response. 
     Heart surgery, e.g., open heart surgery, is another situation wherein a tissue is subjected to the risk of hypoxia and ischemia. The typical open heart surgical procedure involves a prolonged stoppage of the heart and the connection of the patient to a heart-lung machine to provide artificial pumping and gas exchange for the blood. In addition, the surgical procedure itself may also temporarily disrupt the flow of blood in the small vessels that supply the cardiac muscle (e.g., the coronary arteries) with oxygen. As a result, the cardiac muscle is susceptible to hypoxic damage during open heart surgery. Such damage may affect the patient&#39;s chances for full recovery. Without being bound by theory, it is hypothesized that minimization of ischemic damage during open heart surgery will improve patient outcomes and survival. Thus, the use of an aquaporin inhibitor, for example a phenylbenzamide of Formula I, is believed to improve the survival of patients undergoing heart surgery. 
     Edema is the accumulation of excess fluid in a fluid compartment. The accumulation may occur in cells (cellular edema), intercellular spaces within tissues (interstitial edema), or in potential spaces within the body. Cellular edema may be caused by the entry of water into the cells, causing them to swell. It may occur because of decreased osmolality of the fluid surrounding the cells, as in hypotonic fluid overload, or increased osmolality of the intracellular fluid, as in conditions that decrease the activity of the sodium pump of the cell membrane, allowing the concentration of sodium ions within the cell to increase. In particular embodiments of the methods disclosed herein, edema refers to cellular edema. 
     In particular embodiments of the methods disclosed herein, “amount effective to inhibit an aquaporin” or “amount effective to inhibit the aquaporin” is not an amount that has inhibitory action against NF-κB activation. 
     As used herein, “concurrently” means the agents are administered simultaneously or within the same composition. In some embodiments, the compounds are administered simultaneously. In some embodiments, the compounds are administered within the same composition. 
     In one embodiment, provided is a method (Method 1) for treatment or prophylaxis of transplant rejection, inhibiting rejection of transplanted biological material, or prophylaxis, treatment, or control of edema consequent to a transplant, comprising administering to a patient in need thereof, before and/or after the transplant, an effective amount of a phenylbenzamide, e.g., an effective amount of a compound of Formula I: 
     
       
         
         
             
             
         
       
     
     wherein R 1 , R 2 , R 3 , R 4 , and R 5  are selected from H, halogen, halogenated C 1-4  alkyl (e.g., trifluoromethyl), and cyano; and 
     R 6  is H; 
     or a pharmaceutically acceptable salt, prodrug {e.g., wherein R 6  is a physiologically hydrolyzable and acceptable acyl (e.g., acetyl) or a physiologically hydrolyzable and acceptable phosphono (—PO 3 ), which may be substituted, e.g. dibenzylphosphono (—P(═O)(OCH 2 C 6 H 5 ) 2 ), or unsubstituted (—P(═O)(OH) 2 )}, or a pharmaceutically acceptable salt prodrug (e.g., —PO 3   2− Q + Q +  or —PO 3   2− Q 2+ , wherein Q is a pharmaceutically acceptable cation) thereof,

     Phenylbenzamides or produgs thereof, e.g. of Formula I, Formula Ia, or 2-((3,5-bis(trifluoromethyl)phenyl)carbamoyl)-4-chlorophenyl dihydrogen phosphate, as hereinbefore described, may exist in free or salt form, e.g., as acid or base addition salts. In this specification, unless otherwise indicated, language such as “compound of Formula I” or “compound of Formula Ia” or “compound of Formula I or Formula Ia” or “compounds of Formula I or Formula Ia”, is to be understood as embracing the compounds in any form, for example free acid or base addition salt form. Pharmaceutically acceptable salts are known in the art and include salts which are physiologically acceptable at the dosage amount and form to be administered, for example tris(hydroxymethyl)aminomethane salts. 
     The term “prodrug” is a term of art which refers to a compound, which may be active or inactive itself as a pharmaceutical agent, but which under physiological conditions becomes converted to a desired active drug compound, e.g., a compound of Formula I. Typically, this conversion of a prodrug into its active drug involves the hydrolysis (chemically or enzymatically) of a chemical bond such that the prodrug disassociates into the active drug and a by-product. A pharmaceutically acceptable prodrug is one which undergoes this physiological hydrolysis at an acceptable rate in the desired biological tissue and which releases as a by-product a compound which is pharmaceutically acceptable, e.g., non-toxic at the expected dosage at which the prodrug is to be administered. Suitable prodrugs for the compound of Formula I include, but are not limited to, compounds of Formula I wherein the R 6  group is a physiologically hydrolysable and acceptable acyl or phosphono moiety. The benefits of using a prodrug rather than an active drug can be many. For example, the prodrug may be more metabolically stable, have improved pharmacokinetics (e.g., lower clearance, more desirable volume of distribution, more desirable membrane permeability), more desirable tissue localization, better patient tolerability (e.g., side effects), better shelf-life in a pharmaceutical composition, or improved ease of manufacture (e.g., cost, purity, or analysis). Where the physiologically hydrolysable prodrug moiety is itself susceptible to ionization and salt formation, the prodrug itself can form a salt, and this salt may be a pharmaceutically acceptable prodrug salt. 
     The term “patient” includes human or non-human (i.e., animal) patient. In a particular embodiment, the invention encompasses both human and nonhuman. In another embodiment, the invention encompasses nonhuman. In another embodiment, the term encompasses human. 
     The term “fairly rapid” with respect to onset of action means that the time it takes after a compound is administered for a response to be observed is 30 minutes or less, for example 20 minutes or less, for example or 15 minutes or less, for example 10 minutes or less, for example 5 minutes or less, for example 1 minute or less. 
     “Alkyl” is a saturated hydrocarbon moiety, preferably having one to six carbon atoms, preferably having one to four carbon atoms, which may be linear or branched. A “C 1-4 -alkyl” is an alkyl having one to four carbon atoms. 
     “Alkylene” is a saturated hydrocarbon moiety, preferably having one to six carbon atoms, preferably having one to four carbon atoms, which may be linear or branched and which has two points of attachment. A C 1-4 -alkylene is an alkylene having from one to four carbon atoms. For example, C 1 -alkylene is methylene (—CH 2 —). 
     “Carboxy” is —COOH. 
     “Hydroxy” is —OH.

     Example 1: Cardiac Allograft Rejection Model 
     The ability of an APQ inhibitor of the present disclosure to protect against transplant rejection is determined in an intraabdominal heterotopic vascularized cardiac transplantation model between genetically mismatched mice. Four conditions are compared: the use of an APQ4 inhibitor alone, the use of a CTLA4 Ig alone, the combination of an APQ4 inhibitor with a CTLA4 Ig, and a control. 
     APQ4 Inhibitor Protocol 
     The donor mouse (BalbC, fully genetically mismatched with respect to the recipient mouse which is B6,, C57BL/6) is given a 10 mg/kg IP bolus of 2-((3,5-bis(trifluoromethyl)phenyl)carbamoyl)-4-chlorophenyl dihydrogen phosphate in TrisBase 30 minutes prior to surgery. 
     Before removing the heart, the donor is perfused with Ringer&#39;s solution containing 10 μM N-[3,5-bis(trifluoromethyl)phenyl]-5-chloro-2-hydroxybenzamide. After removal from the donor, the heart is stored at 0-4° C. for 8 hours in Ringer&#39;s solution containing 10 μM N-[3,5-bis(trifluoromethyl)phenyl]-5-chloro-2-hydroxybenzamide (Cold Ischemic Storage). 
     30 Minutes prior to surgery, the recipient mouse is given a 10 mg/kg IP bolus of 2-((3,5-bis(trifluoromethyl)phenyl)carbamoyl)-4-chlorophenyl dihydrogen phosphate in TrisBase. The heart is then transplanted into the recipient mouse (B6 mouse) using the vascularized heterotopic cardiac transplantation model. After closing, the recipient mouse receives 10 mg/kg IP injection of 2-((3,5-bis(trifluoromethyl)phenyl)carbamoyl)-4-chlorophenyl dihydrogen phosphate in TrisBase every 6 hours for 5 days. 
     CTLA4 Ig Protocol 
     The recipient mouse (B6) is administered a single dose of Belatacept IP at 10 mg/kg on the day of the transplant surgery as well as a single dose of Belatacept IP at 10 mg/kg 24 hours after surgery. 
     As a negative control, both the donor and recipient mice receive IP administration of TrisBase with neither an APQ4 inhibitor nor a CTLA4 Ig. Results 
     The recipient mice are monitored until their hearts stops beating. The results ( FIG. 1 ) demonstrate that the blockade of APQ4 in addition to CTLA4 Ig treatment results in significantly improved survival. The combination displays a synergistic effect that exceeds the benefit obtained from either treatment regimen alone. For the control mice, all mice are dead within 7 days of surgery. Treatment with CTLA4 Ig alone results in approximately 60% survival after 20 days, about 40% survival after 50 days, and about 13% survival from about 60 days through the end of monitoring at 150 days. Treatment with the APQ4 inhibitor alone results in about 30% survival after 20 days, about 10% survival after 50 days, and about 5% survival from about 60 days through the end of monitoring at 120 days. The combination of the APQ4 protocol with the CTLA4 Ig protocol results in 100% survival through about 30 days, about 60% survival after 50 days, and about 45% survival from about 70 days through the end of monitoring at 150 days. 
     Example 2: Cardiac Explant Experiment 
     This experiment is a model for determining the extent of apoptosis occurring in an explanted heart from BALB/c mice. Hearts are perfused with Ringer&#39;s solution either supplemented with 10 μM of N-[3,5-bis(trifluoromethyl)phenyl]-5-chloro-2-hydroxybenzamide (Compound 1), or without such supplementation. The explanted hearts are then placed in Cold Ischemic Storage (at 0-4° C.) in their respective buffer solutions for 8 hours. The hearts are then photographed and triturated for analysis of apoptosis using Annexin V flow cytometry. Annexin V is used to label phosphatidylserine on the surface of cells, and this is a conventional marker for cells that have undergone apoptosis. It is found that hearts maintained in Ringer&#39;s solution for 8 hours in cold storage show about 46% apoptotic cells. In contrast, hearts maintained in the APQ4-inhibitor supplemented Ringer&#39;s solution show only about 8% apoptotic cells. See  FIG. 2 . In addition,  FIG. 3  shows that a heart maintained in un-supplemented Ringer&#39;s solution shows considerable swelling compared to a heart maintained in supplemented solution.
